Construction of a predictive nomogram. (A, B) Hazard ratio and P value of the constituents involved in univariate and multivariate Cox regression considering clinical parameters and Risk Score in PDAC. (C) Nomogram to predict the 1-year, 3-year, and 5-year overall survival rate of PDAC patients. (D) Calibration curve for the overall survival nomogram model in the discovery group. A dashed diagonal line represents the ideal nomogram. (E) DCA curve was established to evaluate the clinical utility and benefit of the nomogram and additional parameters.
