Kaplan–Meier curve showing the probability of survival without a bleeding event under ECMO depending on anti-Xa value. The cutoff of 0.46 IU/mL is the value with the best sensibility/specificity to predict the occurrence of a hemorrhagic event (Sensibility: 46%, Specificity: 87%, AUROC: 0.65; 95%CI, 0.58–0.73; p = 0.018)
