A ROC curve analysis of MNM and basic and full models for in-hospital death in the development cohort. B The DCA curve indicates that the full model shows a higher net benefit than the basic model in the development cohort. C Calibration curves of the basic model and full model prediction of in-hospital death in the development cohort. D ROC curve analysis of MNM and basic and full models for in-hospital death in the validation cohort. E The DCA curve indicates that the full model shows a higher net benefit than the basic model in the validation cohort. F Calibration curves of the basic model and full model prediction of in-hospital death in the validation cohort
