Kaplan-Meier plot of the 28-day mortality of ARDS patients stratified by plasma mtDNA level. Patients stratified with a ROC-determined cutoff point of 18,640 copies/µL of plasma mtDNA level. The Kaplan-Meier curves showed that survival in patients with plasma mtDNA levels above 18,640 copies/µL was significantly less than that of patients with plasma mtDNA levels less than 18,640 copies/µL (P<0.01).
