^aHigh blood pressure was diagnosed if systolic blood pressure was ≥130 mmHg, diastolic blood pressure ≥85 mmHg, or the subjects was receiving antihypertensive medications.
^bHypertriglyceridemia was diagnosed if triglycerides was ≥ 150 mg/dl in men and women.
^cLow HDL cholesterol was diagnosed if HDL cholesterol was < 40 mg/dl in men and < 50 mg/dl in women.
