bj: partial regression coefficient of each moderator variable. Z: statistic to test the influence of each moderator variable on the prevalence rates. QR: statistic to test the statistical significance of the full model. QE: statistic to test the model misspecification. R2: proportion of variance accounted for by the moderator variables.
