How does a scoping review differ from a systematic review according to the chapter?

A scoping review differs from a systematic review in that it aims to map the existing literature on a topic and identify gaps in research, rather than answering a specific research question with a detailed analysis of the evidence. Scoping reviews are more exploratory and less structured than systematic reviews, which focus on answering specific questions through rigorous methods and quality appraisal of studies.

Scoping reviews are designed to provide an overview of a broad topic, identifying the range of literature available and highlighting areas that require further investigation. In contrast, systematic reviews follow a structured methodology aimed at answering specific research questions, involving comprehensive searches and critical appraisal of included studies to synthesize evidence. This structured approach in systematic reviews is intended to minimize bias and provide reliable conclusions, whereas scoping reviews are more flexible and exploratory in nature.
