  1. Values are means ± SD or n (%). aTwo-sided chi-square test or independent-samples t-test. bP-values < 0.05 are bold. Type 2 diabetes was diagnosed as (1) fasting plasma glucose (FPG) ≥ 7.0 mmol/L; (2) 2 h postprandial glucose ≥11.1 mmol/L; or (3) use of antidiabetes medications. Hypertension was defined as systolic/diastolic blood pressure ≥ 140 mmHg or ≥ 90 mmHg or use of antihypertensive medications. Hypercholesterolemia was defined as use of cholesterol-lowering medications or total serum cholesterol > 200 mg/dl. WBC, white blood cell; FBG, fasting blood glucose; AST, aspartate transaminase; CRE, creatinine; HDL, high-density lipoprotein; LDL, low-density lipoprotein
