Note. Overall tests of model significance were Q(31) =36.98, p = .178; Publication year was grand mean centered. Multi-Center Design is coded dichotomously where 1 = multi-site and 0 = single-site. Placebo Run-In was coded dichotomously where 0 = No Run-In and 1 = Yes. Multivariate analyses used a mixed model (studies random, levels of moderator variables fixed);
