Time-dependent AUCs (area under ROC curve) for pathway-based and gene-based survival prediction models using Wang et al. (2005) dataset (A) and Miller et al. (2005) dataset (B). The AUC measures the overall discriminative abilities of the prediction model over all thresholds. To account for censoring in survival outcome, the method of Heagerty et al. (2000) was used for estimation of AUC.
