How will somebody using The Cochrane Library avoid being confused between Overviews and sub-reviews?
Overviews will be clearly labelled as one of the four types of reviews in The Cochrane Library: Intervention reviews, Diagnostic test reviews, Methodological reviews, and Overviews of reviews. In addition, the differences should be fairly obvious to most users of The Cochrane Library. The format and organization of the text of an Overview will differ from that of a Cochrane review, and the Overview will have a limited number of figures (or none at all), and fewer references than a Cochrane review.
