  1. Values are expressed as median (interquartile range) or n (%). aImmuncompromised status included hematological malignancies, solid tumors, solid-organ transplantation, high-dose or long-term corticosteroids and/or immunosuppressant use, or HIV infection. ARDS, acute respiratory disease syndrome; CS/IS, corticosteroids or immunosuppressants; ECMO, extracorporeal membrane oxygenation; SAPS, simplified acute physiology score; SOFA, sepsis-related organ failure assessment.
