Figure 1

ROC curves for T2D tests, and for early and late onset T2D tests. The dashed and solid lines on the left panel correspond to the ROC curves of T2D tests built by the additive logistic regression model (AUC = 0.606) and the robust optimal ROC curve method (AUC = 0.596). In the right panel, dashed lines correspond to the ROC curves for tests to detect early-onset T2D (AUC = 0.683); solid lines correspond to the ROC curves for tests to detect late-onset T2D (AUC = 0.616).
