k: number of studies. d+: mean effect size. dl and du: lower and upper confidence limits of the 95% confidence interval around the mean effect size. QB: statistic for testing the significance of the moderator variable. QW: statistic for testing the model misspecification. R2: proportion of variance accounted for by the moderator variable.
