Fig. 1. The effects of exposure to caffeine on body weights and food intake in immature and young adult rats. Average body weights in (A) the immature group (p < 0.0001 vs. CT after 1 week) and (B) the young adult group for each week of the study period (p<0.01 vs. CT after 1 week). Average daily food intake in (C) the immature group (p < 0.05 vs. CT) and (D) the young adult group was calculated by dividing the amount of food consumed over one week by seven, and is depicted here for each week. Values are mean ± SD (N = 5/group). Filled circle, CT (control); open circle, CF1 (caffeine 120 mg/kg per day); open triangle, CF2 (caffeine 180 mg/kg per day). Two-way ANOVA test was used for statistical analyses.
