Citations after each trait refer to each study that was meta-analyzed for that trait, k = number of samples meta-analyzed, where all samples for a specific trait were determined to be distinct; k_s = number of published studies from which the samples were taken; r(df = k−1) = estimate of the mean meta-analyzed random effects partner correlation (Pearson’s r for continuous traits; tetrachoric r for dichotomous traits); Cl = Bonferroni-adjusted 95% confidence intervals (adjusting for 22 tests); N = number of total partner pairs meta-analyzed; p-val = p-value, based on two-sided tests, Bonferroni-adjusted for 22 tests; I² = Higgins & Thompson’s I² statistic, a measure of between-/within-study heterogeneity, where overall I² is the proportion of variance in the meta-analysis that is not due to sampling error; τ = the estimated standard deviation of the true effect size (when applicable, heterogeneity values are given for both the within-study and between-study levels, respectively); Prediction Interval = the interval in which the correlations for future meta-analyses of the trait in question are expected to fall. EA = Educational Attainment; IQ score = Intelligence Quotient Score; PAU = Problematic Alcohol Use; Drinking = Drinking Quantity; Smk. = Smoking; SUD = Substance Use Disorder; Agree. = Agreeableness; Consc. = Conscientiousness; Extrav. = Extraversion, Neurot. = Neuroticism; Open. = Openness to Experience; BMI = Body Mass Index; WHR= Waist-to-Hip Ratio; Gen Anx. = Generalized Anxiety.
