Review version search is an Advanced Search for specific published review versions. For example, you can
search only in the reviews published in Issue 4, 2008,
search in all issues of 2007 for reviews from the Stroke group, or
track the development of reviews with more than five included studies since the first issue of CDSR.
It allows specification of detailed search criteria relating to the content of the searched document versions, e.g. where the Declaration of interest section contains the word ‘none’. It enables exporting of specific data from the hits, such as the number of included studies or the Authors’ conclusions section.

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.
