Covidence automatically de-duplicates references upon import. In Import History you can check the number of duplicates as well as any potential errors.
Errors occur due to corrupt data and cannot be imported by Covidence.
Common causes for errors include:
Duplicates refer to copies of kept references. You can review kept references alongside their duplicates by clicking on Check duplicates. By clicking Not a duplicate, the reference will be kept.
Note that if you come across any missed duplicate during either screening process, you have the option to mark it as duplicate at the bottom of the reference.
Complete Imports can only be deleted prior to any actions. If required, navigate to the Review Summary, select Import References, and click on View Details to display the Import History. If available, you can click Undo this import to remove it. Note that this option only allows deletion of the import file in its entirety and not select references.
