Effect of quercetin supplementation on blood glucose levels during oral glucose tolerance test (A), area under the curve (AUC, B) and insulin (C) levels. Values are mean ± SEM, n = 5/6 for each group; SHR and SHR-Zbtb16; control rats, SHR-Q and SHR-Zbtb16-Q; rats supplemented with quercetin; post-hoc Fisher’s least significant difference test of the two-way ANOVA for STRAIN and Q as major factors are indicated as follows: α represents differences in SHR-Q vs. SHR-Zbtb16-Q rats, χ represents differences in SHR vs. SHR-Q rats, β represents differences in SHR vs. SHR-Zbtb16 rats, α, significantly different compared to SHR-Q; β, significantly different compared to SHR-Zbzt16; χ, significantly different compared to SHR-Zbtb16-Q. SHR and SHR-Zbtb16; control rats, SHR-Q and SHR-Zbtb16-Q; rats supplemented with quercetin
