Blood lactate | AUROC | 95%CI | Cut-off | Sensitivity | Specificity | PPV | NPV | Accuracy |
|---|---|---|---|---|---|---|---|---|
Pre-ECMO lactate | 0.685 | 0.582–0.788 | ≥ 5.25 | 75.6% | 62.1% | 60.7% | 76.6% | 68.0% |
Lactate peak | 0.717 | 0.616–0.819 | ≥ 15.15 | 70.8% | 69.0% | 65.4% | 74.1% | 69.8% |
Lactate after 24 h | 0.779 | 0.686–0.871 | ≥ 3.25 | 79.2% | 72.4% | 70.4% | 80.8% | 75.5% |
