Data are presented as mean±s.d. The differences were tested by ANOVA and Bonferroni post hoc test. P<0.05. aThe indicated group versus C group; bThe indicated group versus CAF group; and cThe indicated group versus C-R group. C: control diet; CAF: cafeteria diet; C-R: control diet treated with resveratrol; CAF-R: cafeteria diet treated with resveratrol. OGTT: oral glucose tolerance test; HDL: high-density lipoprotein; VLDL: very-low-density lipoprotein; ANOVA: analysis of variance; s.d.: standard deviation; NA: not applicable
