Abstract: With rising cost of medical research, many clinical trials are carried out with small sample sizes resulting in low power for detecting clinically useful effect size. By pooling the estimated effect sizes from each of the component studies through meta-analytic methods, information from larger number of patients and increased power is expected. Because of its important impact, development of novel methods for meta-analysis has become a rapidly growing field. In this talk, I will review the literature with emphasis on recent developments in multivariate meta-analysis (MMA) and present Ma and Mazumdar (Stat in Med, 2011)’s new method for MMA.
