Table 4:
Leave-one-out validation results of transportability analysis. Values represented are Area under the curve (AUC) and Mann-Whitney U p-value for significant difference between survival prediction classes. Three hospitals in the TCGA dataset are compared to demonstrate the effects of target cohort size. Karnofsky performance score (KPS) was held out as missing/unmeasured data in this model.
