- k number of study outcomes, N total sample size, d effect size (Cohen’s d), 95 % CI 95 % confidence interval around the point estimate of the effect size, Qhomogeneity homogeneity statistic, Qcontrast moderation statistic
- *p < .05, **p < .01, ***p < .001
- aOnly categorical moderators are included in the table; the effects of continuous moderators are described in the text
- bMissings were excluded from moderator analyses. Therefore, sample sizes range from 22 to 27
- cSubgroups with k < 4 excluded from contrast
- dAfter controlling for year of publication and sample size, only type of intervention remained a significant moderator
