N = number of individuals. Values are expressed as mean ± SD, median (Q1, Q3), or number (%). P values indicate statistical significance of the differences among the three groups. BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; LDL-C, low-density lipoprotein cholesterol; FPG, fasting plasma glucose; HPG, 2-hour postprandial blood glucose; HbA1c, hemoglobin A1c; UAER, urinary albumin excretion rate.
