Approach to minimization

A narrative review is:

	a.	A compilation of like studies to address a specific clinical question using a detailed, comprehensive search strategy and rigorous appraisal methods for the purpose of summarizing, appraising, and communicating the results and implications of all the research available on a clinical question. It is the most rigorous approach to minimization of bias in summarizing research.
	b.	A research review that includes published papers that support an author’s particular point of view and usually serves as a general background discussion of a particular issue.
	c.	A general review involving a systematic process. It is more inclusive of studies that are heterogeneous in type of study or sample.
	d.	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.
