This article discusses a proposed risk-based measure of time-varying discrimination for determining the value of predictors in time-to-event models. The discussion focuses on use of the proposed method to determine the added value of intermediate event information for improving prediction of long-term outcomes and an alternative approach for confidence interval estimation.
