Abstract Reviews provide up-to-date, state-of-the-science summaries of the literature and, depending on the journal, may address a wide variety of topics relevant for the readership, such as clinical medicine, public or global health, health policy, biomedical research, or other topics. This chapter describes several types of reviews, including systematic reviews, narrative reviews, scoping reviews, and other types of review articles. It provides guidance on preparing review manuscripts for submission to biomedical journals and discusses factors authors should consider before and when writing a review. A section on guidelines for reviews provides general recommendations for preparing review manuscripts and includes specific guidance for preparing review manuscripts for several major biomedical journals.
