Please note that with databases on Ovid, it is best to use RIS format when exporting from MEDLINE, Embase, or Emcare and the EndNote format when exporting from PsycInfo.
To prepare for screening, we recommend you export your database search results into EndNote.
For stability and ease of use, we suggest you use EndNote Desktop rather than EndNote Web.
If you are new to the program, start by familiarising yourself with EndNote generally. The Library has a range of resources available to support you.
Organise your references |
|
If you plan to deduplicate using EndNote, export records from high quality sources first - as EndNote will send the most recently added records detected as duplicates to the 'Trash', retaining those added first. Databases on Ovid such as MEDLINE are a good place to start, followed by other reputable databases such as CINAHL. Add records from Web of Science and/or Scopus after the key databases with subject headings, and before incomplete/error-prone sources such as Google Scholar.
Exporting references from Ovid Emcare |
When exporting from Ovid Emcare, you may be prompted to use an 'Import Filter'. Select the EMCARE (Ovid) filter. If this does not appear in your list, select 'Other Filters' and search for it. If the filter still does not appear, search for it in the EndNote Import Filters page, which lists new and updated filters to download.
To download and install a filter:
Comprehensive searches often require screening thousands of records. Exporting these from databases to a reference manager is not always straightforward.
Here you will find guidance on how to 'batch' export records from various interfaces to EndNote (you may need to adjust for other reference managers).
General tips:
Recommended maximum per export - 1,500
In this example, there are 3,360 results. You would export this in three batches.
To batch download records to a reference manager, the easiest way is to send a link to the records to your email (maximum 25,000).
The best approach for large numbers of results (maximum 20,000 at a time) is Export Results, visible at the top of the results page when signed in to My Research. Key details needed for deduplication and screening tools - such as authors, year, title, abstract, volume, issue and Digital Object Identifier (DOI) - will be included.
If you need or want additional details from records (such as keywords and language) – you will need to use the time consuming approach of adding records to the temporary folder Selected items page by page, and then exporting out in batches of 1,000 or fewer.
The first option is described here.
Records need to be exported in batches of 100. Databases on Informit can have significant numbers of duplicates, even when searching only one database.
You can export up to 20,000 records at a time from Scopus.
You can export up to 1,000 records at a time from Web of Science.
It is a good habit to back up your EndNote library. Specifically:
Create a back-up library |

Note: Skip this step if you are using Covidence for screening, as Covidence will perform its own deduplication. |
Rename your group |
Before you deduplicate your references in EndNote, rename your groups by adding the total number of results from each database (see example image), for reporting purposes. To rename a group:
The total number of references will need to be reported in your PRISMA flowchart.
|
Deduplicate your references |
Use EndNote's Find Duplicates function to remove multiple copies of references. (X9: References > Find Duplicates; 20: Library > Find Duplicates).
This will change both:

Now that your Library is complete, you can export the references within it to commence screening.
Covidence: you can either export all references in one file and specify the sources later, or export the references for each source separately and select the sources on import, for this to appear in the Covidence PRISMA flowchart. Each file must be under 50 MB (this is about 11,000 references from databases on Ovid).
An export window will appear (for simplicity, we suggest saving to the desktop).
