AUC values of the prediction models (ie, the base-only, longitudinal-only, and full models) when predicting different end points of interest (100-day, 1-year, and 2-year OS) with the St Jude validation data set. The AUC values were obtained by performing bootstrapping 500 times on the validation data. The numbers within the bars are mean AUC values, and the asterisks indicate the significance of the AUC test results (∗∗∗P < .001).
