Kaplan-Meier survival analysis based on lactate concentration. Kaplan–Meier survival curve for survival to hospital discharge between patients with pre-ECMO lactate level above 10.5 mmol/L(red line) and below 10.5 mol/L(blue line). The cumulative survival rate at hospital discharge was significantly higher for patients with a pre-ECMO lactate level of 10.5 mmol/L or less(blue line) compared with patients having a pre-ECMO lactate level greater than 10.5 mmol/L(red line, 93.8% versus 40.0%, respectively; P = 0.01)
