Independent prognostic analysis of risk models. a Independent prognosis -univariate cox analysis results. b The relationship between Schoenfeld residuals and time (Each covariate satisfies the PH risk hypothesis). c Independent prognosis -multivariate cox analysis results. d The 1-, 3-, and 5-year survival rates were predicted by the nomogram (The higher the score, the lower the survival rate). e Calibration curve of nomogram (The closer the slope is to 1, the more accurate the prediction). f ROC curve of the nomogram model
