Figure 3. Construction of a prognostic nomogram for CRC patients. (A and B) Forest plot visualizing the univariate and multivariate Cox regression outcomes of the risk score and diverse clinical features; (C) The integrated nomogram model established based on four independent prognostic factors: age, pathological stage, M stage and individualized risk score; (D) Time-dependent ROC curves assessing the predictive efficiency for 1-year, 3-year and 5-year survival status; (E-G) Calibration curves of the nomogram for survival prediction at the three key time points (1-, 3- and 5-year). CRC: Colorectal cancer; ROC: receiver operating characteristic; AUC: area under the curve.
