Streamlined systematic review: Covidence and its new eligibility criteria feature supporting the PICOS framework
Systematic review is a method of analysis based on a comprehensive pool data, preferably using exactly comparable research studies . It promotes evidence-based decision making through making maximum use of the best available evidence from all available sources.
Subscribed by the Libraries, Covidence is a systematic review management tool helping students and researchers with the following tasks at each stage of the systematic review process.
- Import citations
Users can import references into the shared platform, which works with EndNote, Zotero, Mendeley or other reference management tools that support RIS or PubMed formats.
- Screen titles & abstracts
Screening is made faster with features such as keyword highlighting. Covidence keeps full records of who voted and supports single or dual screeners.
- Screen full text
Users review the full-text of references and decide whether they are relevant and should be included in the analysis. With Covidence, reasons for exclusion and notes for resolving disagreements can be recorded.
- Extract data and perform quality assessment
Users can save time and reduce reworks with the flexibility to create custom templates in assessing quality in methodology and extracting data relevant to the research question.
Users can export the data in common formats, and proceed to other tasks in the review such as meta-analysis or narrative analysis.

New feature on screening criteria:
Previously, Covidence allowed only two categories: inclusion criteria and exclusion criteria. In a recent update, Covidence split those two categories into more detailed elements: Population, Intervention, Comparison, Outcomes, and Study Characteristics (PICOS). PICOS is a widely used and supported framework which helps review teams in refining the protocols to ensure clarity before commencing the work.
Note: If you’ve already used the previous version, the existing inclusion/exclusion criteria can still be found under “Other criteria”.
