Note. Statistics are from models in which influential outliers were removed. k= number of studies, ES=number of effect sizes.
N= 1 influential outlier identified and removed. Hedges’ g and model statistics are reported without this influential outlier.
Data were fit with a three-level model. The sum of the variance components (across levels 2 and 3; i.e., σ2), and the total proportion of variance attributable to heterogeneity in the true effects is provided in the τ2 and I2 columns, respectively.
