Comparison of voluntary ethanol intake by two pairs of rat lines used as genetic models of anxiety. G.E. Da Silva, A. Ramos and R.N. Takahashi. Brazilian Journal of Medical and Biological Research, 37 (10): 1511, 2004.

Figure 2. Comparison of ethanol intake (A) and ethanol preference (B) between spontaneously hypertensive rats (SHR) and Lewis (LEW) rats. The concentration of the ethanol drinking solution was increased from 2 to 4%. Data are reported as g absolute ethanol ingested daily per kg body weight in panel A and as percent of ethanol compared to total fluid intake in panel B. Each point indicates the mean ± SEM of 9-10 animals per group. SHR showed a greater ethanol intake and preference than LEW rats and female rats consumed more ethanol than male rats (P < 0.05, ANOVA).
