Weight, biochemical parameters including glucose homeostasis, lipids, adipocytokines, and inflammatory markers according to the treatment groups.

Data are means±S.D, Key: sita, sitagliptin; AUCglucose, Area under the curve of glucose; HOMA-IR and HOMA-B, homeostasis model assessment of insulin resistance and β-cell function; QUICKI, quantitative insulin check index;†Statistical significance by oneway analysis of variances among groups.‡Post hoc analysis by least significant difference t test (mean difference between two groups: A = Control vs. sita100, B = Control vs. sita250, C = Control vs. sita500, D = sita100 vs. sita250, E = sita100 vs. sita500, F = sita250 vs. sita500, P
