Model 1: prediction model with classical risk factors (). Model 2: specific prediction model: significant factors of Model 1 () + stepwise addition of hemodialysis characteristics to maximize discriminatory accuracy (ROC area) and goodness of fit (Hosmer-Lemeshow test). OR: Odds Ratio and 95% CI in the final cumulative model. ROC area: area under the ROC curve of the model when the factor is added. Hosmer-Lemeshow test: goodness of fit of the model when the factor is added. |
