Construction and evaluation of the nomogram. (A–B) Univariate and multivariate COX regression analyses are used to identify the effect of the NRSHC and clinical factors on the prognosis of HCC. (C) Schematic nomogram of survival outcome prediction for a representative sample. The sample has pTNM stage I, 55 years of age, and is classified as a high-risk group in the NRSHC model, with total score of 74.5, and the predicted 1 -, 3 -, and 5-year mortality rates are 7.47%, 17.2%, and 25.7%, respectively. (D) The calibration curve shows the relationship between the predicted values of the nomogram and the actual values. (E–G) The AUC value of the nomogram and other models at 1, 3, 5 years. (H–J) Clinical net benefit of the nomogram and other models at 1,3,5 years.
