We have made some changes to the way we count the number of studies screened by each reviewer in the 'Title and abstract screening' stage of Covidence. We made these changes to improve the accuracy of the count and to make it easier to understand.
- Previously, when reviewers chose to move a study back to screening, that study's votes still contributed to the count. Now they do not.
- Previously, when a study was marked as a duplicate, that study's votes still contributed to the count. Now they do not.
The following rules now apply to counting each reviewer's contribution:
- “Yes”, “Maybe”, and “No”, including consensus votes, are counted as contributions.
- When a study is moved back to screening, existing votes in screening no longer contribute. (Votes made on the study after it’s moved back to screening do contribute.)
- When a study is marked as a duplicate after votes have been placed, existing votes in screening no longer contribute. (When a study is marked as not being a duplicate, existing votes placed on the review prior to it being marked as a duplicate do contribute.)
