Import RIS Files

RIS files are generated to load studies from search databases other than PubMed into NK. After performing a search on SCOPUS, Web of Science, Embase, etc. there is an option to export the search as an RIS file. It must be exported as an RIS file because that is the format needed for NK to read it correctly.

Make sure you export all the studies in the search. Specific tips on search databases are below.

You may consider downloading Zotero if you are finding it difficult to export RIS files from EndNote.

Generate the RIS File from the Search Engine


  • Export all studies as Format: RIS and Field: “Citation”
  • Unselect “Link to External Resolver” and “URL”


  • Leave all preselected items on “Citation Format” alone
  • Export as “RIS Format”

Other Search Engine

  • Follow the steps in any Search Engine that supports RIS Export
  • When in doubt, select the file type that is 'for Reference Managers' or similar

Log into the specific nest on NK. Go to Literature Search, this is where you normally search automatically on PubMed through NK.

Upload RIS File

  • From the Literature Search page, select “Add Search”
  • In the modal that appears, select “File Import”

  • If your RIS File resulted from a search on an index, enter the full query you used and identify the Search Engine/Index in the drop-down.
  • If the Search Engine of interest is not present, select “Other”. A text box will appear below this menu; enter the search engine name there.
  • Enter the date of your search

Why do you need to add this information?

We use the Query, Search Engine, and Date as part of the record-keeping on where the records you screened came from. You will be able to access this information in the “History” tab on any study, and it also impacts your PRISMA Chart.

  • When done, click “Add” in the bottom right of the modal.

Format for RIS file

If the RIS file does not load any of the studies, check to make sure the RIS file is formatted correctly. Change the file to a .txt file and look at the format. It should be in the format below; if not, edit the file before uploading or contact support.


There is no automatic updating of RIS import. To update your RIS file, we recommend that you do not delete or alter your past import; add an entirely new search term and file; our system will automatically de-duplicate the imported results.

Deleting a RIS File

  • In the Literature Search page, find the line representing your RIS Import by identifying its Term/Query, Search Engine, and/or Date.
  • In the far right column, click the red trash can icon.
  • A warning will appear; if you are certain that you want to delete all records from your RIS Import, and any history of its presence in the nest, click “Proceed.”

Deletion Warning:

If you delete a search or a RIS file, it will remove all studies and associated screening, tagging, and extraction data from the nest. This action cannot be reversed!
