Figure 6. The nomogram to predict probability of OS for CRC patients in all 791 patients. (A) The nomogram for predicting proportion of patients with OS. (B) The calibration plots of the nomogram for the probability of OS at 3 and 5 years. (C) Time-dependent ROC based on the nomogram for survival probability. Nomogram-predicted probability of survival is plotted on the x-axis, and observed survival probability is plotted on the y-axis.
