MEDLINE search strategy
The search strategy gathers together the references from the five potential areas of MEDLINE where they could be found, restricts them to english language publications on human adults and then looks for the study designs: meta-analysis, randomised controlled trial, cohort studies and case control studies. In each case the study design is included as a MeSH heading and a text word.
