Details

The plot shows the observed or imputed effect sizes of the studies with the corresponding 95% confidence intervals. A light gray shadow shows the interval containing 95% of the imputations for studies with Non-statistically Significant Unreported Effects (NSUEs).

The effect size of the hypothesis of the model with the corresponding 95% confidence intervals is added to the bottom of the forest plot.
