γ-glutamyl transferase-to-platelet ratio based nomogram predicting overall survival of gallbladder carcinoma

Figure 1 Kaplan-Meier curves for overall survival stratified according to Gamma-glutamyl transferase–to–platelet ratio.

Figure 2 Kaplan-Meier curves for overall survival of different tumor–node–metastasis stages stratified according to gamma-glutamyl transferase–to–platelet ratio.

Figure 3 Prediction nomogram for survival probability. A: Nomogram for overall survival; B: Calibration curve for the nomogram for predicting 1-year survival probability; C: Calibration curve for the nomogram for predicting 3-year survival probability; and D: Calibration curve for the nomogram for predicting 5-year survival probability.

Figure 4 Time-dependent receiver operating characteristic curves for the nomogram. 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].
