A systematic review is a protocol-driven, rigorous and comprehensive synthesis of existing research, designed to answer a well-defined question. It involves following methodological guidance, and reporting in accordance with specific guidelines. A systematic review requires a substantial time commitment typically taking between 12-18 months to complete. Before undertaking a systematic review, you should strongly consider if you and your team can commit to the time required.
