On the Review Summary screen, select the "Import" button.
Covidence can import the following formats:
EndNote XML format
Export from EndNote - Highlight the reference you wish to export from your EndNote Library. Click File -> Export. Select file type "XML" and output style "Show all Fields". OR to export as a RIS, select file type "Text Only" and output style "RefMan (RIS) Export".
Export from PubMed - Click the Save button. Next, select the Format "PubMed" and create the file. Note that this is different to the usual method of exporting Pubmed citations using "Send to" > "Citation Manager".
RIS text format
Almost every database and citation management program allows for RIS-formated export. Refer to the database/citation management program help for instructions.
Select in what stage of your Review the references should be imported. Normally, you would select "Screen" from the pull-down options.
Use "Choose File" to find the reference file on your computer.
Finally, click the "Import" button.
Once your file is uploaded, you'll be re-directed to your Review Summary page. From here you can monitor the progress of your import.
You can check your import by selecting "View Details" within the "Import References" section.
Covidence automatically de-duplicates during the import process. The process checks for duplicates within the uploading file compared to the previously imported citations.
To identify duplicate references, Covidence checks the title, year, and volume. These must match exactly to trigger removal. The author field is also checked. If authors are similar, the record will be noted as a duplicate.
You can view the duplicates by clicking "Import References" on the "Review Summary" page and then the "# duplicates were removed" link. Citations can be returned to the screening process if you feel the deduplication is in error by clicking on the "not a duplicate" flag.
