βE masks sex differences in binge-like EtOH consumption. (A) Average 2 h intake across 4 day drinking in the dark (DID). (B) Preference for EtOH solution during the 4 h binge test. (C) Consumption of EtOH during the 4 h binge test on day 4 of the DID procedure. A two-way ANOVA revealed a main effect of sex (female mice > male mice) and a sex by genotype interaction. Post hoc analyses indicated that the βE –/– female mice consumed more EtOH than βE –/– male and βE +/+ female mice. Data are presented as means ± SEM.
