  • The analysis included predictors from Table 2 and retained variables with P values <0.10. Note: sex, BMI, and % fat were not retained in the model because they were not significant predictors. Values in the table represent the independent contributions to r2 for each predictor variable in the model. AUC is the area under the curve during the OGTT,

  • * denotes negative correlation, and subscripts indicate the order of entry into the regression model. Log-transformed values for ISI, insulin AUC, and glucose AUC were used for these analyses.
