AUC1 (95% CI) AUC2 (95% CI) AUC3 (95% CI) Increment over age (AUC3-AUC1)
2-year model 0.604 (0.491, 0.718) 0.858 (0.783, 0.932) 0.756 (0.699, 0.884) 0.152
4-year model 0.630 (0.526, 0.735) 0.850 (0.784, 0.917) 0.744 (0.719, 0.871) 0.114
combined model 0.635 (0.532, 0.737) 0.855 (0.790, 0.919) 0.753 (0.729, 0.878) 0.118

AUC, area under the receiver-operator characteristic curve; AUC1, AUC of age alone;

AUC2, AUC of age plus markers; AUC3, overfitting corrected AUC of age plus markers; CI, confidence interval.
