Nomogram to predict the survival outcome of patients with PDAC. A–B Univariable and Multivariable Cox regression were conducted to find prognostic factors of OS in PDAC, red boxes represent P < 0.05 in the forest plots. The clinicopathological features and risk score were analyzed. C The nomogram was drawn to predict 1.5 year, 2 year, and 3 year Oss for PDAC. The higher total point was, the lower survival rates patients will have. D Calibration curve was used to show agreement between actual and nomogram-predicted OSs, the gray diagonal line represented reference line
