According to an article wrote by Maeda et al. (2021), "systematic review is a ‘methodology used systematically to search for and synthesize knowledge generated through empirical studies to inform policy and decision-making and to uncover hidden patterns or trends that exist among relevant studies'(Grant & Booth, 2009)". This approach is usually used to minimized bias in summarizing research and is a form of secondary research.

A meta-analysis is a "statistical approach to synthesizing the results of a number of studies that produce a larger sample size and thus greater power to determine the true magnitude of an effect" (Melnyk & Fineout-Overholt, 2019, p. 171). A systematic review involves many studies to address a specific clinical question while avoiding bias, and meta-analysis is used to analyze the studies into one result.
