Differences in anger and hostility (z-scores) between carriers of different OTXR rs53576 genotypes. Significant differences in anger (p = 0.016) and hostility (p = 0.018) (z-scores) are revealed by the Student’s T test between carriers of AA genotype of OXTR gene (SNP rs53576) and others (G allele carriers) in general sample (N = 1705). These differences were especially pronounced in men (N = 837), whereas within women (N = 868), differences were not statistically significant. Anger. Men: one-way ANOVA (F = 3.06, df = 2, df = 834, p = 0.047), Dunnett T3 test (AA vs. GG, p = 0.031). Women: not significant. Hostility. Men: one-way ANOVA (F = 3.68, df1 = 2, df2 = 834, p = 0.026), Dunnett T3 test (AA vs. GG, p = 0.016). Women: one-way ANOVA (F = 3.096, df = 2, df2 = 865, p = 0.046), Dunnett T3 test (not significant)
