  • ORs are estimated from logistic regression models with adjustment for age, sex, smoking status, and LDL-cholesterol (basic model), and additionally for HOMA-IR (log), BMI, and waist circumference (full model). Unadjusted proportions appear in boldface type.

  • *In these regressions the variable used in the direct definition of the outcome variable (waist circumference or HOMA-IR) was excluded from the adjustment variables.
