C^td-index, time-dependent concordance index.

^aThe model performance (C^td-index) was calculated by employing bootstrapping on the test dataset.

^bp-values represent statistical comparison between each model and the reference model (Transformer-DAPT), determined using bootstrap-based statistical testing with 1000 resamples. Lower p-values indicate significant performance differences compared with the reference model.
