Figure 2

Production of observational-inclusive (category B) reviews by Review Groups in the Cochrane Collaboration. Note for Figure 2: Vertical axis: Actual number of category (B) reviews published in 2008/09 minus the number to be expected given pre-2008 proportions. Horizontal axis: Pre-2008 proportion of category (B) reviews. Example: a negative number means that a review group has produced fewer category (B) reviews in 2008 or 2009 than would be expected from its production prior to 2008.
