A random effects meta-analysis identified a moderate effect of SRIs compared to all control conditions (g=0.50, 95% CI: 0.37, 0.63, z=7.33, p<0.001) (Figure 2). Visual inspection of the forest plot, Q statistic, and I2 statistic identified minimal heterogeneity across SRI trials [Q(10)=5.70 p=0.94, I2=0%]. Visual inspection of the funnel plot and Egger’s test for bias indicated that publication bias was not significant (t=0.98, p=0.35). The analog-to-ANOVA revealed no significant difference between active comparison trials (g=0.78) and non-active comparison trials (g=0.48) [Q(1)=0.94, p=0.33].
