Any piece of primary research ought to be preceded by a systematic review. The key advantage of a systematic review over the traditional narrative review is its ability to identify all the available evidence in a systematic and replicable manner. This book describes the key steps to undertaking a systematic review and the process of undertaking a meta-analysis. It includes step-by-step examples of how to design data extraction forms, search strategies and combine in a meta-analysis.
