Limiting your results
After combining search concepts, the search results can be limited by e.g. language, study type, year, etc. Click on the 'Limits' button and 'Additional Limits' to find all options for limiting a search. Tip! The Special Ovid Filters for Embase (under Additional Limits) are comprised of search strategies instead of only Emtree terms.
Excluding conference abstracts
Besides articles, Embase also includes conference abstracts. These are abstracts of (poster) presentations that were presented during conferences. If this publication type is not relevant, you can exclude these publications:
- First, create a subset of the publication types that you wish to exclude, for instance: conference abstract. (search 2: Limits > Embase status > Conference Abstract status)
- Subtract this subset from the full set with NOT (search 3).

Using Clinical Queries (via Additional Limits) you can limit the results to clinical studies in the following categories:
There are 3 options for each clinical study category: sensitive, specific, and an option with the best balance between sensitivity and specificity.
The Clinical Queries search strategies were designed by the Health Information Research Unit (McMaster University, Canada). View the exact Clinical Queries search terms.
Limiting by RCTs
Cochrane has developed a search filter to restrict results to RCTs in Embase. Below you can find the RCT search filter rewritten in a single line to facilitate reuse.
