Predictive accuracy of the model during follow-up period was measured using the iAUC, a weighted mean of AUC over follow-up period. The time-dependent receiver operating characteristics curve of the NLR-trend was superior to that of NLR-pre (A) (bootstrap iAUC mean difference = 0.036; 95% CI 0.013–0.073), NLR-post (B) (bootstrap iAUC mean difference = 0.045; 95% CI 0.019–0.081) (B) and NLR-delta (C) (bootstrap iAUC mean difference = 0.061; 95% CI 0.025–0.104).
