  • Model 1 adjusted for age, sex, and education. Model 2 adjusted for Model 1 variables plus study field center, smoking status, body mass index, systolic blood pressure, use of antihypertensive medications, total cholesterol, HDL cholesterol, and use of lipid-lowering medications. Model 3 adjusted for model 2 variables plus 2-hour glucose (for markers other than 2-hour glucose) and fasting glucose (for markers other than fasting glucose).

  • *N=2164 for those without diabetes.
