Search Strategy
With the help of an information specialist, we developed search strategies for each clinical practice. We searched MEDLINE, EMBASE, Epistemonikos and the Cochrane Central Register of Controlled Trials from inception to April 2020. We also checked the reference lists of reviews and retrieved articles for additional studies. Since this rapid review aimed to synthesize the evidence based on published studies, we did not search the grey literature. An example of a search strategy for a specific practice in Medline is presented in the Supplementary Digital File 4.
