Descriptive statistics and ANOVA results for DRD4 promoter polymorphisms.

Note. F-statistics, p-values, and ηp2 for both additive and grouped models are shown for the 120-bp duplication, other SNPs were analyzed using additive genetic models unless otherwise noted. Sex was included as a covariate for ImpSS, and sex, ability, and age were included as covariates for CSSQ-S analyses. FA = additive model, FG = grouped model, M = mean, SD = standard deviation. †Homogeneity of variances was violated; therefore, grouped model was tested. dbSNP numbers are identifiers in the NCBI SNP database (http://www.ncbi.nlm.nih.gov/SNP/). Raw data available upon request.
