  • One-way ANOVA revealed no significant difference in age at the beginning of the study (MRI 1) among three groups of subjects (F(2,60) = 1.3, p = 0.28). Repeated-measures ANOVA revealed significant effects of MRI (2 vs 3: F(1,43) = 11.3, p < 0.01) and group (NHD vs HD: F(1,43) = 67.9, p < 0.0001) on ethanol intake with no significant interaction (F(1,43) = 0.06, p = 0.8).
