As shown in Table 4b, in Whites, all four FHDr measures were significantly associated with low P3 amplitude. Further, FHDrPSND–AUDMaxSxCnt (b=−0.38) presented the most robust association. However, among dichotomous measures, only FHFather–AUDDx and FHParent–AUDDx were significantly associated. Interestingly, in Blacks, none of the density or dichotomous measures except FHDrPSND–AUDDx were associated with P3 amplitude. Overall, compared to dichotomous measures, albeit only among Whites, associations of greater magnitude were observed for density measures.
