When you are ready to do your full text screening you will need to add the full text to your records.

Quality Assessment

Covidence only supports a Risk of Bias assessment at the moment.  You have the option to start with the standard Cochrane Risk of Bias domains or to define a custom set of domains for your needs.  

The Cochrane Risk of Bias domains include:

  • sequence generation
  • allocation concealment
  • blinding of participants and personnel
  • blinding of outcome assessment
  • incomplete outcome data
  • selective outcome reporting and ‘other issues’

Quality Assessment videos by Cochrane of Risk and Bias tool: RoB 2.0 tool, parts 1 through 4, inclusive.



The domains that you define for the first study assessed in a review will be used as the template for all the other studies in this review.  So, each subsequent assessment will have the same list of domains as the first assessment.  You can still customize each study independently.
