  1. **p < .01, ***p < .001. Statistical significance indicates the effect size estimate is significantly different from zero. Note. ES = effect size estimate, 95% CI = 95% confidence interval of the pooled effect size estimate; n = the number of effect size estimates in the subgroup; SD = standard deviation. Heterogeneity statistics for the meta-analysis: QB (4) = 7.80, p = .10; QW (100) = 97.63, p = .54.
