A 7 (time) × 2 (gender) × 2 (ADH1B gene status) mixed factorial analysis of variance (ANOVA) was conducted to test whether BrAC varied as a function of ADH1C gene status. Baseline BrAC was not included, as it was a constant. Results indicated a main effect of time (F (6, 55) = 39.94, p < .01; partial η2 = .43) on BrAC, but no significant main effect of ADH1C (F (1, 55) = 0.04, p = .84; partial η2 = .001) or time x ADH1C interaction (F (6, 55) = 0.64, p = .70; partial η2 = .01).
