Bai et al[34]’s model1, tumor–node–metastasis staging, CA 19-9, monocyte–to–lymphocyte ratio, and neutrophil–to–lymphocyte ratio. A: Time-dependent receiver operating characteristic (ROC) curves at 1 year; B: Time-dependent ROC curves at 3 years; and C: Time-dependent ROC curves at 5 years. 1Bai’s model: Nomogram based on jaundice, CA19-9, tumor–node–metastasis stage, and R status[34].
