Most databases can export results in RIS format, which can be imported to Covidence. Suggested workflow:
1. Export references in RIS format from databases and save them in a folder.
2. In folder, create subfolders for each database (eg results from Medline, Web of Science, etc). Keep the original RIS files in case you need them later.
3. Import RIS files into Covidence, which will automatically detect and remove most duplicates.
4. Screen titles/abstracts in Covidence.
5. For any additional duplicates found in Covidence, you can either:
a. simply screen them out
b. tag them, then manually adjust the numbers in the PRISMA diagram generated by Covidence.
6. When finished screening full text in Covidence, you can export included studies to citation management software. From Review Settings, select Export, Included, then choose which manager.
Up to 10,000 results may be exported at a time from ProQuest databases:
Create and log into My Research account. Once logged in, you'll see a link to Export Results:

Then, choose RIS as the format, and be sure to change Fields to Citation, Abstract. The RIS file will download. Save it to the folder you’ve created for your review, inside the subfolder for the database (eg Medline, Embase).
At the top of the search results, click Share, then Email a link to download exported results (up to 25,000):
On the following page, enter your email and select RIS format. Please note that there have been intermittent problems reported with receiving the emailed search results - check your Junk folder, and ask your librarian if you don't receive the email.
Up to 1000 results may be exported at once:
Ensure that you include the abstract in your export:
Some databases and most websites do not support exporting results in RIS format. As a workaround:
To import references from a citation manager:
Our citation management guide can help you decide which citation manager to use, and you can find the instructions for importing references to your preferred citation manager below:
After completing your reference import, Covidence will search for duplicates. If any are identified, these will automatically be suppressed and a 'Duplicates' button will appear.
You can check that Covidence de-duplicated correctly by:
If you accidentally import references, you can go to Import > Import History to undo the import:
