Number of systematic reviews included 849
Summary of Findings 5% of reviews in the Cochrane database and the Database of abstract of reviews of effects between 1994 and 2011 focused on adverse effects. Whilst some improvements in literature searches were apparent, such as an increase in the number of databases searched and fewer date and language restrictions applied there was an increase in reviews limited to data from randomized controlled trials. The reporting of search strategies could still be improved further, with only 9% of the included reviews reporting reproducible searches.
