Evaluation of the accuracy of the mean effect sizes estimated using the methods SOMA and MAMA as compared to REMA, according to the Root Mean Square Error (RMSE), Bias (Estimated value—True value), and coverage of the 95% confidence interval (CI). Each point corresponds to one scenario. Red dashed lines indicate the median value of RMSE (A, B), zero bias (C, D), the target value 0.95 of the confidence interval (E, F)
