HOMA-IR: homeostasis model assessment-insulin resistance, I: normotensive control, II: hypertensive control, III: group treated with vit C, IV: group treated with vit A, V: group treated with vit E, and VI: group treated with all the vitamins. Values are expressed as mean ± SD; . aP < 0.01 when compared with group II, bP < 0.05 when compared with group II, cP < 0.01 when compared with group I, and dP < 0.05 when compared with group I by Dunnette’s multiple comparison test.
