Systematic Reviews: Covidence

This guide provides information and resources which may be helpful when undertaking a systematic review or other type of knowledge synthesis.

Covidence

 

 

 

 

Covidence is a cloud-based tool to streamline the process of reviewing titles and abstracts for large-scale literature reviews enabling you to:

  • Collaboratively manage an unlimited amount of references and PDFs
  • Customize screening, full-text review, critical appraisal, and data extraction
  • Document each step of your review process for transparent reporting (including an automatically updated PRISMA diagram)

Accessing Covidence

 

  1. Request an invitation to join the "Mayo Clinic Library Covidence" account.
  2. Accept the email invitation that you receive to create your account (check that it didn't go in your junk mail).
  3. Going forward, login via the Covidence sign-in page.
     

Note about Importing with an EndNote XML file

Use the All Fields output style in EndNote when creating an export file to import into Covidence.

Other output styles may result in studified references. This occurs when records that reference the same study are automatically merged. Studified/merged references affect record numbers required for accurate PRISMA reporting.

Manage Settings

Be sure to save changes made under these tabs!

Review Settings -> Edit the title of your review and change the number of reviewers (note: systematic review guidelines require 2 reviewers). 

Reviewers -> Invite additional team members (reviewers will need to accept the invitation in their email in order for the review to appear in their My Reviews list; reviewers do not need to be affiliated with Mayo Clinic to join the team). 

Team Settings -> Control which reviewers are assigned to screen studies or resolve conflicts and track progress of each reviewer.

Criteria & Exclusion Reasons -> Create list of inclusion criteria for title and abstract screening (may also manage exclusion reasons with customized drop-down list of exclusion criteria for use during the full text review).  Additionally, keywords may be added to highlight certain words that could indicate inclusion or exclusion.  

Study Tags -> Covidence is pre-populated with 2 tags: Ongoing Study & Awaiting Classification.  Additional tags may be added and used to quickly filter references.  Tags are visible by other team members.

Using Covidence for Data Extraction

*For Covidence users, it's advised to review the Data Extraction Video (~ 1 hr.) and Step-by-Step Guide before proceeding with developing a data extraction template. The Q&A video may also be helpful.

To use the data extraction template in Covidence, select the studies for extraction from the Review Summary screen. The Data Extraction Template button brings up an example template with an editing function and preview pane or you may create a template from scratch. Be sure to save any firm changes. Once the template has been developed, publish it to provide access to the other reviewers on the team.  Changes may be made after extraction has begun although this will require returning to studies for further review, extraction and consensus.
