GSTM1 and acute respiratory distress syndrome: In the multivariate logistic regression model, the PaO2/FiO2 (OR, 0.993; 95%CI, 0.989–0.996; P < 0.001), the Hb (OR, 0.989; 95%CI, 0.981–0.998; P=0.012), the NLR (OR, 1.042; 95%CI, 1.025–1.060; P < 0.001), the lactate (OR, 1.160; 95%CI, 1.063–1.265; P=0.001), and the vasoactive drugs (OR, 2.504; 95% CI, 1.601–3.917; P < 0.001) were covariates statistically associated with the requirement of IMV in ARDS patients (Table S3, Table 3).
