From: Prone positioning in severe ARDS requiring extracorporeal membrane oxygenation
Propensity score matched pair patient assignment. *Matching was performed for age, sex, SOFA score, the duration of MV before ECMO, and performance of prior PP before ECMO. ECMO, extracorporeal membrane oxygenation; MV, mechanical ventilation; PP, prone positioning; SOFA, Sequential Organ Failure Assessment
