Type: article

Abstract: Meta-analysis is the statistical procedure for combining data from multiple studies.Meta-analyses are being conducted with increasing frequency (Figure 1).Compared to a single clinical study, they can increase statistical power, improve accuracy, and provide a summary of findings with respect to key clinical questions.Understanding the statistical models underlying the analysis is important.Most meta-analyses are based on 1 of 2 statistical models, the fixed-effect model or the random-effects model.
