Data presented mean (standard deviation) or median with range. FPG = fasting plasma glucose, FPI = fasting plasma insulin, HOMA-IR = homeostatic assessment for IR, IR = insulin resistance, TC = total cholesterol, TG = triglycerides. P values for unpaired t-test (normally distributed data) and Mann–Whitney U test (nonparametric data). P values in bold are significant at <0.05.
