Figure 3. Construction and verification of a predictive nomogram. (A) Univariate and multivariate Cox regression suggested the prognostic model and age were independent prognostic predictors. (B) The nomogram for OS prediction in HCC patients at 1, 3, and 5 years. (C–E) Calibration curves of nomogram for OS prediction at 1, 3, and 5 years. (F–H) ROC curves to evaluate the predictive performance of nomogram. (I–K) DCA curves to evaluate the clinical decision-making benefits of nomogram.
