What characteristic distinguishes a systematic review from other types of literature reviews?

A systematic review is characterized by its use of a structured and predefined method for analyzing and synthesizing research findings. This approach ensures that every step of the review process is transparent, reproducible, and comprehensive, allowing for a meticulous evaluation of the existing literature on a specific topic or research question. Unlike other types of literature reviews which may rely on subjective interpretations or may lack a systematic approach, the methodology in systematic reviews is guided by explicit criteria for selecting studies, assessing their quality, and synthesizing their results. This rigorous process enhances the validity and reliability of the conclusions drawn, making systematic reviews valuable resources in evidence-based practice and decision-making.
