(a) The time-dependent ROC curve of the simplified (twice) random survival forest model at 1 year (12 months), with an AUC of 0.995. (b) The time-dependent ROC curve of the simplified (twice) random survival forest model at 3 years (36 months), with an AUC of 0.999. (c) The time-dependent ROC curve of the simplified (twice) random survival forest model at 5 years (60 months), with an AUC of 0.993. (d) Marginal effects of variables included in the simplified (twice) random survival forest model on the recurrence-free survival probability.
