Values are expressed as mean (SD), and when not normally distributed, they were ln-transformed for analysis and are expressed as medians (IQR). SD: standard deviation; IQR: interquartile range. Comparisons were done between the three groups using analysis of variance (ANOVA) and Kruskal-Wallis. If there was statistically significant, multiple comparisons were made by least significant difference (LSD) test. Group NGT consisted of 32 normal glucose tolerant subjects; group IGR consisted of 33 impaired glucose tolerant and/or impaired fasting glucose subjects; group DM consisted of 31 newly diagnosed diabetes mellitus subjects. BMI: body mass index; WC: waist circumference; SBP: systolic blood pressure; DBP: diastolic blood pressure; SF: serum ferritin; FPG: fasting plasma glucose; OGTT: oral glucose tolerance test; 2 hPG: 2 h plasma glucose; FTI: fasting true insulin; TG: triglycerides; HDL-C: high density lipoprotein cholesterol; HOMA: homeostasis model assessment; HOMA-IR: homeostasis model assessment of insulin resistance; HOMA-β: homeostasis model assessment of beta cell function. Compared with group NGT ,  compared with group IGR .
