Review version search is an Advanced Search for specific published review versions. It allows specification of detailed search criteria relating to the content of the searched document versions. The results can be exported as specific data from the hits, such as the number of included studies or the Authors' conclusions section.
For example, you can
- search only in reviews where the Declaration of interest section contains the word 'none'.
- search only in the reviews published in Issue 4, 2008,
- search in all issues of 2007 for reviews from the Stroke group.
IMPORTANT: The full functionality of Review Version Search is only available for review versions in RevMan 5 format - which means 2009 and onwards. Reviews in RevMan 4 format will not return any results for any of the queries relating to review content.

Warning: You cannot use a single string containing information from several different review elements. For instance, since references are stored in a highly structured format, the search string 'New England Journal of Medicine 1977;297:686-91' contains information from several different elements and the punctuation is added when displaying the review.
Warning: Numbers in the Data and Analysis section cannot be used as search terms as all the numbers are stored in a way that prevents this.
