Figure 4. Establishment of a nomogram and ROC analysis. (A, B) The forest plot of the univariate and multivariate Cox regression. (C) A nomogram combining clinicopathological variables and risk score predicts 1-, 3-, and 5-year OS of ESCA patients. (D) The ROCs curve for different clinicopathological variables. (E–G) The ROCs curve for 1-, 3-, and 5-year survival time training, testing, and entire groups are based on the risk score. (H–J) Calibration curve of the nomogram to predict the probability of the 1-, 3-, and 5-year OS.
