Calibration curve of the model for predicting in-hospital all-cause mortality in TAAAD. The calibration plot showed that the calibration curve (Apparent line) closely matched the diagonal (Ideal line), indicating good calibration of the predictive model. In addition, internal validation of the predictive model using bootstrap resampling showed that the corrected curve (Bias-corrected line) almost overlapped with the diagonal, suggesting good accuracy of the nomogram model
