Significance of Heterogeneity
Heterogeneity, as defined by Science, pertains to the differences observed in results among various studies included in systematic reviews and meta-analyses. This variation can arise from differing study populations, interventions, or methodologies, and it can significantly impact the overall conclusions drawn from the research. When high levels of heterogeneity are present, they may lead to misleading results, thereby complicating the synthesis of evidence across studies. Understanding heterogeneity is essential for accurate interpretation of research findings.
