Carriers of one or two copies of block 1, haplotype 3, ACTATGTTGTTATAATAT, had significantly higher mean alcohol sedative effects scores (5.32, SE = 0.43) than non-carriers [mean = 2.69 (SE = 0.34), after adjusting for time, BAC, and age (F(1, 49) = 4.94, p=0.0309)]. In contrast, carriers of one or two copies of block 1, haplotype 4, ACGATGTTGTTATAATAT, had significantly lower mean alcohol sedative effects scores (2.76, SE = 0.40) than non-carriers [mean = 4.84 (SE = 0.36)], after adjusting for time, BAC, and age (F(1, 49) = 7.62, p=0.0081) (Table 5).
