Abbreviation: AUC, area under the curve.

Model 1: adjusted for age, smoking, exercise, and family history of diabetes.

Model 2: model 1 + additional adjustment for body mass index.

Model 3: model 1 + additional adjustment for waist circumference.

Model 4: model 1 + additional adjustment for body mass index and waist circumference.
