The MANCOVA revealed a significant effect of group on network connectivity strength (F(14,326)=2.910, p<0.001, partial η2 = 0.111); univariate tests showed that the HC and age- and gender-matched ALC groups differed on connectivity strength for four networks (LECN: F = 5.348, p = 0.021; sensorimotor (SM): F = 5.177, p = 0.024; basal ganglia (BG): F = 14.234, p < 0.001; primary visual (V1): F = 5.171, p= 0.024) indicating that chronic alcohol use, not age was driving these network differences (Table 2, Figures 3-4).
