Fig. 4From: Oxytocin receptor gene polymorphism (rs53576) and digit ratio associates with aggression: comparison in seven ethnic groupsSex differences in BPAQ subscales (z-scores) (at the bottom). BPAQ scales (z-scores): PA—physical aggression, VA—verbal aggression, AN—anger, HT—hostility. Sex differences are statistically significant (Student’s T test): PA (p < 0.001), VA (p < 0.001), AN (p = 0.004), HT (p = 0.032)Back to article page
