Fig. 4: Brain response to neutral faces in T-PRS-based LV1 regions as a mediator of the relationship between T-PRS and anhedonia.

Brain response to neutral faces in T-PRS-based LV1 regions mediated the relationship between T-PRS and anhedonia in females (ab = 0.093, SE = 0.047, 95% CI [0.019; 0.198]) but not males (ab = 0.008, SE = 0.033, 95% CI [−0.061; 0.076]).
