Search strategies:
Searches were carried out using Ovid search software for all databases other than the Cochrane Library, and followed fundamentally the same structure. With the exception of the basic Embase strategy, the following examples list the Medline versions of the strategies used. Notes have been added at the end of strategies where other databases differed substantially.
