Parameters that influenced the risk of respiratory failure, and therefore the need for mechanical ventilation (13/51), were NT-proBNP (p = 0.007), troponin (p = 0.0016), high-density lipoprotein (HDL) (p = 0.0405), lymphocytes (p = 0.0246), hemoglobin (p = 0.0095), hematocrit (p = 0.0032), PLT (p = 0.0004), PCT (p = 0.013), ferritin (p = 0.0020), D-dimers (p = 0.0019), and EF (p = 0.0014). The gene discussed is NPPB; the disease is respiratory failure.
