Table 2:
Predicted and observed mortalities by additive and logistic EuroSCORE risk levels for the entire patient cohort
| Patients (deaths) | Observed mortality rate (95% CI) | Predicted mortality rate (95% CI) | Recalibration | P-value | |

| Low risk (0–3) | 26 (1) | 3.8 (−4.1–11.8) | 3.0 (3.0–3.0) | 1.28 | 0.23 |
| Medium risk (4–6) | 219 (9) | 4.1 (1.5–6.8) | 5.0 (4.9–5.1) | 0.83 | |
| High risk (7+) | 183 (24) | 13.1 (8.3–18.1) | 8.6 (8.3–8.8) | 1.53 | |

ªPatients were divided into three approximately equal risk tertiles for logistic EuroSCORE analysis.
