Tools for Systematic Reviews
Managing the selection process can be challenging, particularly in a large-scale systematic review that involves multiple reviewers. There are various free and subscription-based tools available that support the study selection process ( Cochrane Handbook, 4.6.6.1 ).
This page describes various tools available to help conduct a systematic review. The University of Tasmania has access to EndNote, Covidence and JBI SUMARI.
Covidence is an online systematic review program developed by, and for, systematic reviewers. It can import citations from reference managers like EndNote, facilitate the screening of abstracts and full-text, populate risk of bias tables, assist with data extraction, and export to all common formats.
Covidence Demo video [3:24]
Covidence is a core component of Cochrane's review production toolkit and has also been endorsed by JBI.
Access to UTAS Covidence account
If you are the project leader, follow these steps to create a UTAS Covidence account:
- Create a UTAS Covidence account Step-by-step instructions on how to create at UTAS Covidence account
Once you have created your UTAS Covidence account, you can create a review and invite others to join the review.
If you are not the project leader, please wait for your invitation from your project leader to join the review (you don't need to create a UTAS Covidence account).

5 software tools to support your systematic review processes
By Dr. Mina Kalantar on 19-Jan-2021 13:01:01

Systematic reviews are a reassessment of scholarly literature to facilitate decision making. This methodical approach of re-evaluating evidence was initially applied in healthcare, to set policies, create guidelines and answer medical questions.
Systematic reviews are large, complex projects and, depending on the purpose, they can be quite expensive to conduct. A team of researchers, data analysts and experts from various fields may collaborate to review and examine incredibly large numbers of research articles for evidence synthesis. Depending on the spectrum, systematic reviews often take at least 6 months, and sometimes upwards of 18 months to complete.
The main principles of transparency and reproducibility require a pragmatic approach in the organisation of the required research activities and detailed documentation of the outcomes. As a result, many software tools have been developed to help researchers with some of the tedious tasks required as part of the systematic review process.
hbspt.cta._relativeUrls=true;hbspt.cta.load(97439, 'ccc20645-09e2-4098-838f-091ed1bf1f4e', {"useNewLoader":"true","region":"na1"});
The first generation of these software tools were produced to accommodate and manage collaborations, but gradually developed to help with screening literature and reporting outcomes. Some of these software packages were initially designed for medical and healthcare studies and have specific protocols and customised steps integrated for various types of systematic reviews. However, some are designed for general processing, and by extending the application of the systematic review approach to other fields, they are being increasingly adopted and used in software engineering, health-related nutrition, agriculture, environmental science, social sciences and education.
Software tools
There are various free and subscription-based tools to help with conducting a systematic review. Many of these tools are designed to assist with the key stages of the process, including title and abstract screening, data synthesis, and critical appraisal. Some are designed to facilitate the entire process of review, including protocol development, reporting of the outcomes and help with fast project completion.
As time goes on, more functions are being integrated into such software tools. Technological advancement has allowed for more sophisticated and user-friendly features, including visual graphics for pattern recognition and linking multiple concepts. The idea is to digitalise the cumbersome parts of the process to increase efficiency, thus allowing researchers to focus their time and efforts on assessing the rigorousness and robustness of the research articles.
This article introduces commonly used systematic review tools that are relevant to food research and related disciplines, which can be used in a similar context to the process in healthcare disciplines.
These reviews are based on IFIS' internal research, thus are unbiased and not affiliated with the companies.

This online platform is a core component of the Cochrane toolkit, supporting parts of the systematic review process, including title/abstract and full-text screening, documentation, and reporting.
The Covidence platform enables collaboration of the entire systematic reviews team and is suitable for researchers and students at all levels of experience.
From a user perspective, the interface is intuitive, and the citation screening is directed step-by-step through a well-defined workflow. Imports and exports are straightforward, with easy export options to Excel and CVS.
Access is free for Cochrane authors (a single reviewer), and Cochrane provides a free trial to other researchers in healthcare. Universities can also subscribe on an institutional basis.
Rayyan is a free and open access web-based platform funded by the Qatar Foundation, a non-profit organisation supporting education and community development initiative . Rayyan is used to screen and code literature through a systematic review process.
Unlike Covidence, Rayyan does not follow a standard SR workflow and simply helps with citation screening. It is accessible through a mobile application with compatibility for offline screening. The web-based platform is known for its accessible user interface, with easy and clear export options.
Function comparison of 5 software tools to support the systematic review process
Eppi-reviewer.
EPPI-Reviewer is a web-based software programme developed by the Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI) at the UCL Institute for Education, London .
It provides comprehensive functionalities for coding and screening. Users can create different levels of coding in a code set tool for clustering, screening, and administration of documents. EPPI-Reviewer allows direct search and import from PubMed. The import of search results from other databases is feasible in different formats. It stores, references, identifies and removes duplicates automatically. EPPI-Reviewer allows full-text screening, text mining, meta-analysis and the export of data into different types of reports.
There is no limit for concurrent use of the software and the number of articles being reviewed. Cochrane reviewers can access EPPI reviews using their Cochrane subscription details.
EPPI-Centre has other tools for facilitating the systematic review process, including coding guidelines and data management tools.
CADIMA is a free, online, open access review management tool, developed to facilitate research synthesis and structure documentation of the outcomes.
The Julius Institute and the Collaboration for Environmental Evidence established the software programme to support and guide users through the entire systematic review process, including protocol development, literature searching, study selection, critical appraisal, and documentation of the outcomes. The flexibility in choosing the steps also makes CADIMA suitable for conducting systematic mapping and rapid reviews.
CADIMA was initially developed for research questions in agriculture and environment but it is not limited to these, and as such, can be used for managing review processes in other disciplines. It enables users to export files and work offline.
The software allows for statistical analysis of the collated data using the R statistical software. Unlike EPPI-Reviewer, CADIMA does not have a built-in search engine to allow for searching in literature databases like PubMed.
DistillerSR
DistillerSR is an online software maintained by the Canadian company, Evidence Partners which specialises in literature review automation. DistillerSR provides a collaborative platform for every stage of literature review management. The framework is flexible and can accommodate literature reviews of different sizes. It is configurable to different data curation procedures, workflows and reporting standards. The platform integrates necessary features for screening, quality assessment, data extraction and reporting. The software uses Artificial Learning (AL)-enabled technologies in priority screening. It is to cut the screening process short by reranking the most relevant references nearer to the top. It can also use AL, as a second reviewer, in quality control checks of screened studies by human reviewers. DistillerSR is used to manage systematic reviews in various medical disciplines, surveillance, pharmacovigilance and public health reviews including food and nutrition topics. The software does not support statistical analyses. It provides configurable forms in standard formats for data extraction.
DistillerSR allows direct search and import of references from PubMed. It provides an add on feature called LitConnect which can be set to automatically import newly published references from data providers to keep reviews up to date during their progress.
The systematic review Toolbox is a web-based catalogue of various tools, including software packages which can assist with single or multiple tasks within the evidence synthesis process. Researchers can run a quick search or tailor a more sophisticated search by choosing their approach, budget, discipline, and preferred support features, to find the right tools for their research.

Web-Based Software Tools for Systematic Literature Review in Medicine: Systematic Search and Feature Analysis
Kathryn cowie.
1 Nested Knowledge, Saint Paul, MN, United States
Asad Rahmatullah
Nicole hardy, kevin kallmes, associated data.
Supplementary Table 1: Screening Decisions for SR (systematic review) Tools Reviewed in Full.
Supplementary Table 2: Inter-observer Agreement across (1) Systematic Review (SR) Tools and (2) Features Assessed.
Systematic reviews (SRs) are central to evaluating therapies but have high costs in terms of both time and money. Many software tools exist to assist with SRs, but most tools do not support the full process, and transparency and replicability of SR depend on performing and presenting evidence according to established best practices.
This study aims to provide a basis for comparing and selecting between web-based software tools that support SR, by conducting a feature-by-feature comparison of SR tools.
We searched for SR tools by reviewing any such tool listed in the SR Toolbox, previous reviews of SR tools, and qualitative Google searching. We included all SR tools that were currently functional and required no coding, and excluded reference managers, desktop applications, and statistical software. The list of features to assess was populated by combining all features assessed in 4 previous reviews of SR tools; we also added 5 features (manual addition, screening automation, dual extraction, living review, and public outputs) that were independently noted as best practices or enhancements of transparency and replicability. Then, 2 reviewers assigned binary present or absent assessments to all SR tools with respect to all features, and a third reviewer adjudicated all disagreements.
Of the 53 SR tools found, 55% (29/53) were excluded, leaving 45% (24/53) for assessment. In total, 30 features were assessed across 6 classes, and the interobserver agreement was 86.46%. Giotto Compliance (27/30, 90%), DistillerSR (26/30, 87%), and Nested Knowledge (26/30, 87%) support the most features, followed by EPPI-Reviewer Web (25/30, 83%), LitStream (23/30, 77%), JBI SUMARI (21/30, 70%), and SRDB.PRO (VTS Software) (21/30, 70%). Fewer than half of all the features assessed are supported by 7 tools: RobotAnalyst (National Centre for Text Mining), SRDR (Agency for Healthcare Research and Quality), SyRF (Systematic Review Facility), Data Abstraction Assistant (Center for Evidence Synthesis in Health), SR Accelerator (Institute for Evidence-Based Healthcare), RobotReviewer (RobotReviewer), and COVID-NMA (COVID-NMA). Notably, of the 24 tools, only 10 (42%) support direct search, only 7 (29%) offer dual extraction, and only 13 (54%) offer living/updatable reviews.
Conclusions
DistillerSR, Nested Knowledge, and EPPI-Reviewer Web each offer a high density of SR-focused web-based tools. By transparent comparison and discussion regarding SR tool functionality, the medical community can both choose among existing software offerings and note the areas of growth needed, most notably in the support of living reviews.
Introduction
Systematic review costs and gaps.
According to the Centre for Evidence-Based Medicine, systematic reviews (SRs) of high-quality primary studies represent the highest level of evidence for evaluating therapeutic performance [ 1 ]. However, although vital to evidence-based medical practice, SRs are time-intensive, taking an average of 67.3 weeks to complete [ 2 ] and costing leading research institutions over US $141,000 in labor per published review [ 3 ]. Owing to the high costs in researcher time and complexity, up-to-date reviews cover only 10% to 17% of primary evidence in a representative analysis of the lung cancer literature [ 4 ]. Although many qualitative and noncomprehensive publications provide some level of summative evidence, SRs—defined as reviews of “evidence on a clearly formulated question that use systematic and explicit methods to identify, select and critically appraise relevant primary research, and to extract and analyze data from the studies that are included” [ 5 ]—are distinguished by both their structured approach to finding, filtering, and extracting from underlying articles and the resulting comprehensiveness in answering a concrete medical question.
Software Tools for Systematic Review
Software tools that assist with central SR activities—retrieval (searching or importing records), appraisal (screening of records), synthesis (content extraction from underlying studies), and documentation/output (presentation of SR outputs)—have shown promise in reducing the amount of effort needed in a given review [ 6 ]. Because of the time savings of web-based software tools, institutions and individual researchers engaged in evidence synthesis may benefit from using these tools in the review process [ 7 ].

Existing Studies of Software Tools
However, choosing among the existing software tools presents a further challenge to researchers; in the SR Toolbox [ 8 ], there are >240 tools indexed, of which 224 support health care reviews. Vitally, few of these tools can be used for each of the steps of SR, so comparing the features available through each tool can assist researchers in selecting an SR tool to use. This selection can be informed by feature analysis; for example, a previously published feature analysis compared 15 SR tools [ 9 ] across 21 subfeatures of interest and found that DistillerSR (Evidence Partners), EPPI-Reviewer (EPPI-Centre), SWIFT-Active Screener (Sciome), and Covidence (Cochrane) support the greatest number of features as of 2019. Harrison et al [ 10 ], Marshall et al [ 11 ], and Kohl et al [ 12 ] have completed similar analyses, but each feature assessment selected a different set of features and used different qualitative feature assessment methods, and none covered all SR tools currently available.
The SR tool landscape continues to evolve; as existing tools are updated, new software is made available to researchers, and new feature classes are developed. For instance, despite the growth of calls for living SRs, that is, reviews where the outputs are updated as new primary evidence becomes available, no feature analysis has yet covered this novel capability. Furthermore, the leading feature analyses [ 9 - 12 ] have focused on the screening phase of review, meaning that no comparison of data extraction capabilities has yet been published.
Feature Analysis of Systematic Review Tools
The authors, who are also the developers of the Nested Knowledge platform for SR and meta-analysis (Nested Knowledge, Inc) [ 13 ], have noted the lack of SR feature comparison among new tools and across all feature classes (retrieval, appraisal, synthesis, documentation/output, administration of reviews, and access/support features). To provide an updated feature analysis comparing SR software tools, we performed a feature analysis covering the full life cycle of SR across software tools.
Search Strategy
We searched the SR tools for assessment in 3 ways: first, we identified any SR tool that was published in existing reviews of SR tools (Table S1 in Multimedia Appendix 1 ). Second, we reviewed SR Toolbox [ 8 ], a repository of indexed software tools that support the SR process. Third, we performed a Google search for Systematic review software and identified any software tool that was among the first 5 pages of results. Furthermore, for any library resource pages that were among the search results, we included any SR tools mentioned by the library resource page that met our inclusion criteria. The search was completed between June and August 2021. Four additional tools, namely SRDR+ (Agency for Healthcare Research and Quality), Systematic Review Assistant-Deduplication Module (Institute for Evidence-Based Healthcare), Giotto Compliance, and Robotsearch (Robotsearch), were assessed in December 2021 following reviewer feedback.
Selection of Software Tools
The inclusion and exclusion criteria were determined by 3 authors (KK, KH, and KC). Among our search results, we queued up all software tools that had descriptions meeting our inclusion criteria for full examination of the software in a second round of review. We included any that were functioning web-based tools that require no coding by the user to install or operate, so long as they were used to support the SR process and can be used to review clinical or preclinical literature. The no coding requirement was established because the target audience of this review is medical researchers who are selecting a review software to use; thus, we aim to review only tools that this broad audience is likely to be able to adopt. We also excluded desktop applications, statistical packages, and tools built for reviewing software engineering and social sciences literature, as well as reference managers, to avoid unfairly casting these tools as incomplete review tools (as they would each score quite low in features that are not related to reference management). All software tools were screened by one reviewer (KC), and inclusion decisions were reviewed by a second (KK).
Selection of Features of Interest
We built on the previous comparisons of SR tools published by Van der Mierden et al [ 9 ], Harrison et al [ 10 ], Marshall et al [ 11 ], and Kohl et al [ 12 ], which assign features a level of importance and evaluate each feature in reference screening tools. As the studies by Van der Mierden et al [ 9 ] and Harrison et al [ 10 ] focus on reference screening, we supplemented the features with features identified in related reviews of SR tools (Table S1 in Multimedia Appendix 1 ). From a study by Kohl et al [ 12 ], we added database search, risk of bias assessment (critical appraisal), and data visualization. From Marshall et al [ 11 ], we added report writing.
We added 4 more features based on their importance to software-based SR: manual addition of records, automated full-text retrieval, dual extraction of studies, risk of bias (critical appraisal), living SR, and public outputs. Each addition represents either a best practice in SR [ 14 ] or a key feature for the accuracy, replicability, and transparency of SR. Thus, in total, we assessed the presence or absence of 30 features across 6 categories: retrieval, appraisal, synthesis, documentation/output, administration/project management, and access/support.
We adopted each feature unless it was outside of the SR process, it was required for inclusion in the present review, it duplicated another feature, it was not a discrete step for comparison, it was not necessary for English language reviews, it was not necessary for a web-based software, or it related to reference management (as we excluded reference managers from the present review). Table 1 shows all features not assessed, with rationale.

Feature Assessment
To minimize bias concerning the subjective assessment of the necessity or desirability of features or of the relative performance of features, we used a binary assessment where each SR tool was scored 0 if a given feature was not present or 1 if a feature was present. Tools were assessed between June and August 2021. We assessed 30 features, divided into 6 feature classes. Of the 30 features, 77% (23/30) were identified in existing literature, and 23% (7/30) were added by the authors ( Table 2 ).

Evaluation of Tools
For tools with free versions available, each of the researchers created an account and tested the program to determine feature presence. We also referred to user guides, publications, and training tutorials. For proprietary software, we gathered information on feature offerings from marketing webpages, training materials, and video tutorials. We also contacted all proprietary software providers to give them the opportunity to comment on feature offerings that may have been left out of those materials. Of the 8 proprietary software providers contacted, 38% (3/8) did not respond, 50% (4/8) provided feedback on feature offerings, and 13% (1/8) declined to comment. When providers provided feedback, we re-reviewed the features in question and altered the assessment as appropriate. One provider gave feedback after initial puplication, prompting issuance of a correction.
Feature assessment was completed independently by 2 reviewers (KC and AR), and all disagreements were adjudicated by a third (KK). Interobserver agreement was calculated using standard methods [ 19 ] as applied to binary assessments. First, the 2 independent assessments were compared, and the number of disagreements was counted per feature, per software. For each feature, the total number of disagreements was counted and divided by the number of software tools assessed. This provided a per-feature variability percentage; these percentages were averaged across all features to provide a cumulative interobserver agreement percentage.
Identification of SR Tools
We reviewed all 240 software tools offered on SR Toolbox and sent forward all studies that, based on the software descriptions, could meet our inclusion criteria; we then added in all software tools found on Google Scholar. This strategy yielded 53 software tools that were reviewed in full ( Figure 1 shows the PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses]-based chart). Of these 53 software tools, 55% (29/53) were excluded. Of the 29 excluded tools, 17% (5/29) were built to review software engineering literature, 10% (3/29) were not functional as of August 2021, 7% (2/29) were citation managers, and 7% (2/29) were statistical packages. Other excluded tools included tools not designed for SRs (6/29, 21%), desktop applications (4/29, 14%), tools requiring users to code (3/29, 10%), a search engine (1/29, 3%), and a social science literature review tool (1/29, 3%). One tool, Research Screener [ 20 ], was excluded owing to insufficient information available on supported features. Another tool, the Health Assessment Workspace Collaborative, was excluded because it is designed to assess chemical hazards.

Overview of SR Tools
We assessed the presence of features in 24 software tools, of which 71% (17/24) are designed for health care or biomedical sciences. In addition, 63% (15/24) of the analyzed tools support the full SR process, meaning they enable search, screening, extraction, and export, as these are the basic capabilities necessary to complete a review in a single software tool. Furthermore, 21% (5/34) of the tools support the screening stage ( Table 3 ).
Breakdown of software tools for systematic review by process type (full process, screening, extraction, or visualization; n=24).
Data Gathering
Interobserver agreement between the 2 reviewers gathering data features was 86.46%, meaning that across all feature assessments, the 2 reviewers disagreed on <15% of the applications. Final assessments are summarized in Table 4 , and Table S2 in Multimedia Appendix 2 shows the interobserver agreement on a per–SR tool and per-feature basis. Interobserver agreement was ≥70% for every feature assessed and for all SR tools except 3: LitStream (ICF; 53.3%), RevMan Web (Cochrane; 50%), and SR Accelerator (Institute for Evidence-Based Healthcare; 53.3%); on investigation, these low rates of agreement were found to be due to name changes and versioning (LitStream and RevMan Web) and due to the modular nature of the subsidiary offerings (SR Accelerator). An interactive, updatable visualization of the features offered by each tool is available in the Systematic Review Methodologies Qualitative Synthesis.
Feature assessment scores by feature class for each systematic review tool analyzed. The total number of features across all feature classes is presented in descending order.
Giotto Compliance (27/30, 90%), DistillerSR (26/30, 87%), and Nested Knowledge (26/30, 87%) support the most features, followed by EPPI-Reviewer Web (25/30, 83%), LitStream (23/30, 77%), JBI SUMARI (21/30, 70%), and SRDB.PRO (VTS Software) (21/30, 70%).
The top 16 software tools are ranked by percent of features from highest to lowest in Figure 2 . Fewer than half of all features are supported by 7 tools: RobotAnalyst (National Centre for Text Mining), SRDR (Agency for Healthcare Research and Quality), SyRF (Systematic Review Facility), Data Abstraction Assistant (Center for Evidence Synthesis in Health, Institute for Evidence-Based Healthcare), SR-Accelerator, RobotReviewer (RobotReviewer), and COVID-NMA (COVID-NMA; Table 3 ).

Stacked bar chart comparing the percentage of supported features, broken down by their feature class (retrieval, appraisal, extraction, output, admin, and access), among all analyzed software tools.
Feature Assessment: Breakout by Feature Class
Of all 6 feature classes, administrative features are the most supported, and output and extraction features are the least supported ( Figure 3 ). Only 3 tools, Covidence (Cochrane), EPPI-Reviewer, and Giotto Compliance, offer all 4 extraction features ( Table 4 ). DistillerSR and Giotto support all 5 retrieval features, while Nested Knowledge supports all 5 documentation/output features. Colandr, DistillerSR, EPPI-Reviewer, Giotto Compliance, and PICOPortal support all 6 appraisal features.

Heat map of features observed in 24 analyzed software tools. Dark blue indicates that a feature is present, and light blue indicates that a feature is not present.
Feature Class 1: Retrieval
The ability to search directly within the SR tool was only present for 42% (10/24) of the software tools, meaning that for all other SR tools, the user is required to search externally and import records. The only SR tool that did not enable importing of records was COVID-NMA, which supplies studies directly from the providers of the tool but does not enable the user to do so.
Feature Class 2: Appraisal
Among the 19 tools that have title/abstract screening, all tools except for RobotAnalyst and SRDR+ enable dual screening and adjudication. Reference deduplication is less widespread, with 58% (14/24) of the tools supporting it. A form of machine learning/automation during the screening stage is present in 54% (13/24) of the tools.
Feature Class 3: Extraction
Although 75% (18/24) of the tools offer data extraction, only 29% (7/24) offer dual data extraction (Giotto Compliance, DistillerSR, SRDR+, Cadima [Cadima], Covidence, EPPI-Reviewer, and PICOPortal [PICOPortal]). A total of 54% (13/24) of the tools enable risk of bias assessments.
Feature Class 4: Output
Exporting references or collected data is available in 71% (17/24) of the tools. Of the 24 tools, 54% (13/24) generate figures or tables, 42% (10/24) of tools generate PRISMA flow diagrams, 32% (8/24%) have report writing, and only 13% (3/34) have in-text citations.
Feature Class 5: Admin
Protocols, customer support, and training materials are available in 71% (17/24), 79% (19/24), and 83% (20/24) of the tools, respectively. Of all administrative features, the least well developed are progress/activity monitoring, which is offered 67% (16/24) of the tools, and comments, which are available in 58% (14/24) of the tools.
Feature Class 6: Access
Access features cover both collaboration during the review, cost, and availability of outputs. Of the 24 software tools, 83% (20/24) permit collaboration by allowing multiple users to work on a project. COVID-NMA, RobotAnalyst, RobotReviewer, and SR-Accelerator do not allow multiple users. In addition, of the 24 tools, 71% (17/24) offer a free subscription, whereas 29% (7/24) require paid subscriptions or licenses (Covidence, DistillerSR, EPPI-Reviewer Web, Giotto Compliance, JBI Sumari, SRDB.PRO, and SWIFT-Active Screener). Only 54% (13/24) of the software tools support living, updatable reviews.
Principal Findings
Our review found a wide range of options in the SR software space; however, among these tools, many lacked features that are either crucial to the completion of a review or recommended as best practices. Only 63% (15/24) of the SR tools covered the full process from search/import through to extraction and export. Among these 15 tools, only 67% (10/15) had a search functionality directly built in, and only 47% (7/15) offered dual data extraction (which is the gold standard in quality control). Notable strengths across the field include collaborative mechanisms (offered by 20/24, 83% tools) and easy, free access (17/24, 71% of tools are free). Indeed, the top 4 software tools in terms of number of features offered (Giotto Compliance, DistillerSR, Nested Knowledge, and EPPI-Reviewer all offered between 83% and 90% of the features assessed. However, major remaining gaps include a lack of automation of any step other than screening (automated screening offered by 13/24, 54% of tools) and underprovision of living, updatable outputs.
Major Gaps in the Provision of SR Tools
Marshall et al [ 11 ] have previously noted that “the user should be able to perform an automated search from within the tool which should identify duplicate papers and handle them accordingly” [ 11 ]. Less than a third of tools (7/24, 29%) support search, reference import, and manual reference addition.
Study Selection
Screening of references is the most commonly offered feature and has the strongest offerings across features. All software tools that offer screening also support dual screening (with the exception of RobotAnalyst and SRDR+). This demonstrates adherence to SR best practices during the screening stage.
Automation and Machine Learning
Automation in medical SR screening has been growing. Some form of machine learning or other automation for screening literature is present in over half (13/24, 54%) of all the tools analyzed. Machine learning/screening includes reordering references, topic modeling, and predicting inclusion rates.
Data Extraction
In contrast to screening, extraction is underdeveloped. Although extraction is offered by 75% (18/24) tools, few tools adhere to SR best practices of dual extraction. This is a deep problem in the methods of review, as the error rate for manual extraction without dual extraction is highly variable and has even reached 50% in independent tests [ 16 ].
Although single extraction continues to be the only commonly offered method, the scientific community has noted that automating extraction would have value in both time savings and improved accuracy, but the field is as of yet underdeveloped. To quote a recent review on the subject of automated extraction, “[automation] techniques have not been fully utilized to fully or even partially automate the data extraction step of systematic review” [ 21 ]. The technologies to automate extraction have not achieved partial extraction at a sufficiently high accuracy level to be adopted; therefore, dual extraction is a pressing software requirement that is unlikely to be surpassed in the near future.
Project Management
Administrative features are well supported by SR software. However, there is a need for improved monitoring of review progress. Project monitoring is offered by 67% (16/24) of the tools, which is among the lowest of all admin features and likely the feature most closely associated with the quality of the outputs. As collaborative access is common and highly prized, SR software providers should recognize the barriers to collaboration in medical research; lack of mutual awareness, inertia in communication, and time management and capacity constraints are among the leading reasons for failure in interinstitutional research [ 22 ]. Project monitoring tools could assist with each of these pain points and improve the transparency and accountability within the research team.
Living Reviews
The scientific community has made consistent demands for SR processes to be rendered updatable, with the goal of improving the quality of evidence available to clinicians, health policymakers, and the medical public [ 23 , 24 ]. Despite these ongoing calls for change, living, updatable reviews are not yet standard in SR software tools. Only 54% (13/24) of the tools support living reviews, largely because living review depends on providing updatability at each step up through to outputs. However, until greater provision of living review tools is achieved, reviews will continue to fall out of date and out of sync with clinical practice [ 24 ].
Study Limitations
In our study design, we elected to use a binary assessment, which limited the bias induced by the subjective appeal of any given tool. Therefore, these assessments did not include any comparison of quality or usability among the SR tools. This also meant that we did not use the Desmet [ 25 ] method, which ranks features by level of importance. We also excluded certain assessments that may impact user choices such as language translation features or translated training documentation, which is supported by some technologies, including DistillerSR. We completed the review in August 2021 but added several software tools following reviewer feedback; by adding expert additions without repeating the entire search strategy, we may have missed SR tools that launched between August and December 2021. Finally, the authors of this study are the designers of one of the leading SR tools, Nested Knowledge, which may have led to tacit bias toward this tool as part of the comparison.
By assessing features offered by web-based SR applications, we have identified gaps in current technologies and areas in need of development. Feature count does not equate to value or usability; it fails to capture benefits of simple platforms, such as ease of use, effective user interface, alignment with established workflows, or relative costs. The authors make no claim about superiority of software based on feature prevalence.
Future Directions
We invite and encourage independent researchers to assess the landscape of SR tools and build on this review. We expect the list of features to be assessed will evolve as research changes. For example, this review did not include features such as the ability to search included studies, reuse of extracted data, and application programming interface calls to read data, which may grow in importance. Furthermore, this review assessed the presence of automation at a high level without evaluating details. A future direction might be characterizing specific types of automation models used in screening, as well as in other stages, for software applications that support SR of biomedical research.
The highest-performing SR tools were DistillerSR, EPPI-Reviewer Web, and Nested Knowledge, each of which offer >80% of features. The most commonly offered and robust feature class was screening, whereas extraction (especially quality-controlled dual extraction) was underprovided. Living reviews, although strongly advocated for in the scientific community, were similarly underprovided by the SR tools reviewed here. This review enables the medical community to complete transparent and comprehensive comparison of SR tools and may also be used to identify gaps in technology for further development by the providers of these or novel SR tools.
This review of web-based software review software tools represents an attempt to best capture information from software providers’ websites, free trials, peer-reviewed publications, training materials, or software tutorials. The review is based primarily on publicly available information and may not accurately reflect feature offerings, as relevant information was not always available or clear to interpret. This evaluation does not represent the views or opinions of any of the software developers or service providers, except those of the authors. The review was completed in August 2021, and readers should refer to the respective software providers’ websites to obtain updated information on feature offerings.

The program comprises two components; a web-based annotation tool that allows participants in a review to collaboratively screen citations for relevance, and machine learning technologies that semi-automate this process.
- EndNote Use EndNote to store, deduplicate and screen references.
- Screenatron The Screenatron is a tool designed to allow fast abstract screening when performing a systematic review.
- Disputatron The Disputatron is a tool designed to automatically detect screening disagreements between reviewers of a systematic review, who screened in EndNote.
- Excel Excel is the most basic tool for the management of the screening and data extraction stages of the systematic review process. Customized workbooks and spreadsheets can be designed for the review process, and lists of references can be exported from citation managers into Excel format for screening.
- Rayyan Rayyan helps screen studies for systematic style reviews by automatically identifying disagreements and allowing the use of keywords to help identify relevant studies. Rayyan also has a mobile app for iPhone, iPad and android devices.

The software will improve productivity significantly and help achieve superior results for specific projects and business goals.
- Effect size calculator This is a web-based effect-size calculator. It is designed to facilitate the computation of effect-sizes for meta-analysis. Four effect-size types can be computed from various input data: the standardized mean difference, the correlation coefficient, the odds-ratio, and the risk-ratio.
- Systematic Review Toolbox Use the Data Extraction checkbox to find more tools for extracting data from studies.
- RobotReviewer RobotReviewer is a tool designed to automatically extract information about bias (using the Cochrane Risk of Bias tool), and can also extract information about the participants, interventions, and outcomes studied in a trial.
- RevMan RevMan facilitates preparation of protocols and full reviews, including text, characteristics of studies, comparison tables, and study data. It can perform meta-analysis of the data entered, and present the results graphically.
- CAMARADES: Meta-Analysis Tool A web application for meta-analysis of preclinical data. Functions include: Effect size calculation (NMD/SMD/odds ratio) ; Stratified meta-analysis ; Meta-regression ; Trim-and-fill analysis ; Egger's regression ; Graphs demonstration
- MAGICapp Develop and publish well-structured electronic guidelines, evidence summaries and decision aids. This tool is used post review to facilitate drilling down and examine the primary studies used in the review. No install or setup required.
- GRADEpro "GRADEpro GDT is an easy to use, all‐in‐one web solution to summarise and present information for healthcare decision making. It supports creating summary tables for systematic reviews and health technology assessments. It also provides a database of GRADE evidence tables and health care recommendations for adoption, adaptation and development of new guidelines." (website)
- PRISMA 2009 Flow Diagram
- PRISMA 2020 Statement The PRISMA 2020 statement consists of a 27-item checklist of items recommended for reporting in systematic reviews, an expanded checklist that details reporting recommendations for each item, the PRISMA 2020 abstract checklist , and revised flow diagrams for original and updated reviews .

In addition to the programs described below, some collaborative networks offer additional tools for reviewers. Check out Cochrane tools and software from the Joanna Briggs Institute .

Queen’s University Library provides access to an institutional subscription to Covidence. See the Covidence Institutional Access page for more information.
Covidence website
"Covidence is a not-for-profit service working in partnership with Cochrane to improve the production and use of systematic reviews for health and wellbeing. As systematic reviewers ourselves, we were frustrated at the systems available to reviewers to produce timely, high-quality evidence - so we've dedicated ourselves to making tools that make systematic reviewing faster, easier and more enjoyable!"
- Import citations : "Covidence works seamlessly with your favourite reference managers like EndNote, Zotero, Refworks, Mendeley or any tool that support RIS, CSV or PubMedXML formats."
- Screen titles and abstracts : "Breeze through screening with keyword highlighting & a lightning quick interface. Covidence keeps full records of who voted and also supports single or dual screeners. You can even do it on your mobile when you have a few spare minutes."
- Upload references : "Transfer PDFs stored in your reference manager to Covidence in a few clicks."
- Screen full text : "Decide quickly on studies in full text. Capture reasons for exclusion and any notes so you can resolve any disagreements quickly, with a click of a button."
- Create forms : "Be in control and stay focussed on your PICO question. Customisable extraction forms means you only spend time extracting what you need. It saves you time and money."
- Risk of bias : "Automatically populate your risk of bias tables by highlighting and commenting on text directly in your PDF. No more cut and paste."
- Do data extraction : "Extract data efficiently with a side-by-side view of your customised form and PDF. Then, when you’re done, easily compare your form with other reviewers."
- Export : "Covidence exports to all the common formats so you can continue your review in your preferred software."

Rayyan website
"Rayyan is a 100% FREE web application to help systematic review authors perform their job in a quick, easy and enjoyable fashion. Authors create systematic reviews, collaborate on them, maintain them over time and get suggestions for article inclusion."
Systematic Review Toolbox website
"The Systematic Review Toolbox is a community-driven, searchable, web-based catalogue of tools that support the systematic review process across multiple domains. The resource aims to help reviewers find appropriate tools based on how they provide support for the systematic review process. Users can perform a simple keyword search (i.e. Quick Search) to locate tools, a more detailed search (i.e. Advanced Search) allowing users to select various criteria to find specific types of tools and submit new tools to the database. Although the focus of the Toolbox is on identifying software tools to support systematic reviews, other tools or support mechanisms (such as checklists, guidelines and reporting standards) can also be found."
SR-Accelerator from Bond University is a suite of tools to speed up steps in the Systematic Review (SR) process. It is freely available for anyone in the world to use. The SRA is a modular design which means the tools can be incorporated into existing SR workflows and combined with other automation tools. Current tools are being continually reviewed and refined with additional tools being developed
SRDR website
"In an effort to reduce the burden of conducting systematic reviews, researchers and developers at the Brown University Evidence-based Practice Center (EPC), with support from the Agency for Healthcare Research and Quality (AHRQ), have developed a collaborative, Web-based repository of systematic review data. This resource serves as both an archive and data extraction tool and is shared among organizations and individuals producing systematic reviews worldwide, enabling the creation of a central database of systematic review data which may be critiqued, updated, and augmented on an ongoing basis. This database is freely accessible to facilitate evidence reviews and thus improve and speed up policy-making with regards to healthcare."
