When a file is imported to your review, Covidence will automatically check for duplicates within the imported file, as well as against all studies previously imported to that review. The version of the study imported first will be used in your review; all subsequent versions will be sent to the duplicates list.
To identify duplicates, Covidence uses title, year, volume, and authors. You can read more details about this here.
