Deduplication of References

We recommend using a citation manager to remove duplicate articles before importing your references into Covidence.  Covidence automatically removes some duplicates, but it is not perfect.

We recommend using a citation manager to remove duplicates, though Covidence removes some.

To check the number of duplicate articles Covidence removed, click on the Import Studies button at the top of your review.  On the Import History tab, you will be able to see how many duplicates were removed and verify their accuracy.

You can instruct Covidence to keep an article it has marked as a duplicate.

If you click the Check duplicates button, Covidence will show you the duplicate articles and allow you to select Not a duplicate if you want to keep an article for screening.

Tagging References

All Covidence projects come pre-populated with two tags: Ongoing Study, and Awaiting Classification. To use tags, simply check the box to the left-hand side of those citations you wish to tag.

Adding tags

You can add a new tag to this list by typing your term in the "Tag with:" field and clicking "create new".  

Adding new tag by typing term in the "tags" field and clicking "create new".

Once created and applied to references, you can also filter by these tags. This can be especially useful to get a quick count of how many references received each tag. 

Filter by tags

Tags (as well as any notes entered) are included in exports to Excel/CSV files. For this reason, they are also visible to your co-reviewers.

Linking Full Text to References

Citations must be in the Full Text level in Covidence for you to add PDFs to them. You can bulk upload PDFs using Endnote or Mendeley.  To manually attach full-text PDFs for your full-text screening stage, follow the steps below:
1. Locate and save the PDFs for your articles. You can type the article title into Google Scholar on the HSL website to get the Find@UNC link or a free PDF elsewhere online.
2. Go into the Full Text Screening stage of your Covidence Review.  Select Upload full text for the article.

Select "upload full text"

3. Locate the PDF on your computer and save.

4. A link to the PDF will now appear under the Full Text tab.
