| LV impairment | Mild | Mod/severe | Mod/severe | Mod/severe | Mod/severe | Severe |
| Lactate | <2 | <2 | <2 | 2–5 | >5 | >5 |
| BE | >−0.5 | >−0.5 | <−0.5 | <−0.5 | <−0.5 | <−4 |
| 30-day mortality (%) | 1.2 | 4.1 | 13.6 | 29.4 | 64.2 | 87.5 |
| 30-day mortality (%) if not intubated | 0.7 | 2.3 | 11.2 | 23.4 | 55.6 | 62.5 |
Data from 943 patients classified according to the SAVE criteria, AUC for 30-day mortality 0.814 (0.782 to 0.845), p < 0.001, SBP: systolic blood pressure, LV: left ventricle, BE: base excess, and AUC: area under the curve.
