Meta-analysis

Meta-analysis is a statistical methodology for combining results of multiple studies by using the effect size statistic. Meta-analysis has been used to make comparisons of treatment outcomes for different methods of psychotherapy. In general, these studies have found that little or no variance in outcomes can be explained by the method of therapy.
