^aWC cutoff was set at 88 cm for men and 82 cm for women

^bThe fasting subjects correspond to those shown in Table 1

^cSubjects receiving medication for any of hypertension, hyperglycemia, and dyslipidemia were excluded

^dBased on the χ² test

^eDefined as systolic blood pressure ≥ 130 mmHg and/or diastolic blood pressure ≥ 85 mmHg

^fNo. of those with WC at and above the cutoff/no. of those with risk factor

^gNo. of those with WC below the cutoff/no. of those without risk factor

^hDefined as HDL-cholesterol < 40 mg/dL

ⁱDefined as hemoglobin A1c ≥ 5.5%
