None of the patients were under extracorporeal membrane oxygenation. The median for blood sampling was 4 days after ICU admission. No patient with the ο variant was included in the study.
BMI, body mass index; COPD, chronic obstructive pulmonary disease; CRP, C-reactive protein; LOS, length of stay; MPV, mean platelet volume; SAPS II, simplified acute physiology score; SOFA, sepsis-related organ failure assessment.
