Risk of developing diabetes associated with SI and AIR by ethnicity, sex, glucose tolerance status, BMI and age categories, and family history of diabetes. Estimates are expressed for a 1-SD unit change. Age, sex, ethnicity, center, BMI, IGT, family history of diabetes, SI, and AIR were all included as independent variables in all eight models. Log-transformed values of SI and AIR were used to improve discrimination and calibration of the models and to minimize the influence of extreme observations.
