Heterogeneity: the issue of apples, oranges and fruit pie.

M Purgato1, C E Adams.   

Abstract

Heterogeneity refers to any kind of variation among studies contributing to the same outcome in a systematic review. There are three broad types of heterogeneity: clinical heterogeneity, methodological heterogeneity and statistical heterogeneity. In this paper, we describe these three types of heterogeneity and the main statistical approaches to measure heterogeneity.
