Resumen	A narrative review is a broad, author-directed synthesis of published literature on a topic, written to summarize, interpret, and contextualize existing knowledge without following the rigorous, pre-registered search and selection protocols that characterize systematic reviews. It draws on the author's expertise to weave disparate sources into a coherent account that identifies themes, debates, and directions for future research.	A rapid review is a systematic synthesis method that accelerates the evidence review process by streamlining or omitting certain systematic review steps while maintaining transparent, reproducible methodology. Pioneered by Khangura et al. (2012) and codified by the Cochrane Collaboration (2020), rapid reviews answer urgent policy or clinical questions in weeks to months rather than 12-18 months required by full systematic reviews. Methodological shortcuts—such as single screening of borderline studies, abbreviated search strategies, or limiting study designs—trades some rigor for speed. Rapid reviews are increasingly vital in responding to public health emergencies (pandemics, environmental crises) and evolving clinical practice questions where waiting for a full systematic review is not feasible.
