  • *The reference category is normal (systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg).

  • †The reference category is desirable (serum cholesterol level <5.17 mmol/L [200 mg/dL]).

  • ‡The reference category is a fasting serum glucose level of less than 6.99 mmol/L (126 mg/dL).
