Table 3 Predictive ability of the EuroSCORE risk score model and comparision with suggested modified systems.
From: Creatinine clearance versus serum creatinine as a risk factor in cardiac surgery
Model | Area under the ROC curve | SD |
|---|---|---|
(i) original EuroSCORE weights, „simple additive" version (locally calibrated) | 0.753 | 0.018 |
(ii) original EuroSCORE weights, „logistic" version (locally calibrated) | 0.757 | 0.018 |
(iii) all EuroSCORE variables with weights from institute specific regression | 0.776 | 0.018 |
(iv) same as model (iii) but CC as continuous value substituted for serum creatinine | 0.786 | 0.017 |
(v) same as model (iii) but CC as binarized value (threshold >55 ml/min) substituted for serum creatinine | 0.787 | 0.017 |
