The Cochrane Musculoskeletal Group (CMSG), one of 50 groups of the not-for-profit international Cochrane Collaboration, prepares, maintains, and disseminates systematic reviews of treatments for musculoskeletal diseases. To enhance the quality and usability of systematic reviews, the CMSG has developed tailored methodological guidelines for authors of CMSG systematic reviews. ⋯ Systematic reviews need to be conducted according to high methodological standards. These recommendations on developing and performing a systematic review will help improve consistency among CMSG reviews.
