Moderation analyses identified no effect of sex as defined by percent of men in the study (β = 0.00, SE = 0.00, ns), and no effect of race/ethnicity as defined by percent of non-Caucasian participants (β = 0.001, SE = 0.0, ns). Study sample size did significantly moderate the effect (β = -0.001, SE = 0.00, p < .05), with larger studies demonstrating smaller effects relative to smaller studies.
