Construct clinical nomogram. (A and F) Forest plot showed multivariate Cox regression results for age, stage, grade and risk score; (B and G) Clinical variables (age, stage, grade) and risk score were used to construct a nomogram risk model to predict the patient’s 3-, 5-, and 7-year prognosis; (C and H) ROC curves showed nomogram model predicting patient 3-, 5-, 7-year prognosis; (D and I) Calibration curve of nomogram model predicting patient prognosis; (E and J) Clinical benefit of decision curve analysis comparing single clinical variable and nomogram model in predicting patient prognosis
