From: The clinical significance of blood lactate levels in evaluation of adult patients with veno-arterial extracorporeal membrane oxygenation

Blood lactate	AUROC	95%CI	Cut-off	Sensitivity	Specificity	PPV	NPV	Accuracy
Pre-ECMO lactate	0.879	0.809–0.948	≥ 5.25	86.0%	84.8%	87.5%	83.0%	83.0%
Lactate peak	0.889	0.825–0.953	≥ 14.65	81.7%	89.1%	90.7%	78.8%	84.9%
Lactate after 24 h	0.930	0.878–0.983	≥ 3.25	88.3%	97.8%	98.1%	86.5%	92.5%
