Searching for specific trial types
To retrieve results of specific trial types you can limit your search after you have completed it. This is an easy way to highlight the best type of evidence for specific question types
After finalising your search
Click on the Additional Limits button
The easiest limit to use is the Clinical Queries option. Clinical Queries are listed as question types, therapy, diagnosis, prognosis etc as well as a review option. Using Clinical Queries will limit the results of the search to the best evidence for the question type you select.
Then click Limit
You can see above that this limit has dramatically reduced the search results
