In particular, patients in the SoC group had a higher PaO2/FiO2 at baseline (median 381, IQR 300–467 mmHg) and were less frequently diagnosed with pneumonia (68.1% of them); had lower LDH, AST, CRP, and ferritin; and higher neutrophils and lymphocytes count than the other three groups. The gene discussed is CRP; the disease is susceptibility to pneumonia measurement.
