Note: Significant (p<.05) moderators are shown in boldface font. B represents the change in the effect size for every one-unit change in the moderator. For dummy-coded categorical variables, B represents the difference between estimated effects for each group; for contrast-coded categorical variables, B represents the difference between the group in question and the average estimated effect. If df < 4, there is a twofold greater risk of making a Type I error. The listed p value represents the significance of the moderator in question. When there were not enough studies to estimate an effect, NA is listed in the column for B.
