OR, odds ratio; CI, confidence interval; CS, corticosteroid; IS, immunosuppressant; HCT, hematocrit; WBC, white blood cell; SO₂, oxygen saturation; PaO₂, partial pressure of oxygen; PaCO₂, carbon dioxide; BE, base excess; NLR, neutrophil-to-lymphocyte ratio.

P values less than 0.2 in univariate analysis and less than 0.05 in multivariate analysis were highlighted in bold type.
