For each meta-analytic relationship, we report the total sample size
across all studies (N), the total number of independent studies associated
with the reported relationship (k), and the sample-weighted correlation
(rxy). The 95% confidence interval was used to determine whether effect
sizes were statistically significant. Specifically, confidence intervals that
did not include zero were deemed statistically significant. To assess if
a single population of effect sizes could be assumed, we calculated the
Q-value. A significant Q-value indicates greater than chance variation in
