AHR also remained an independent predictor of hospital mortality in model 1 which was non-adjusted (OR 1.03 [95% CI 1.01–1.05]; p = 0.012) and model 2 was adjusted for age, sex, smoking status, NEWS score (OR 1.03 [95% CI 1.01–1.05); p = 0.036), model 3, which was adjusted for the variables in model 2 plus RF type, DM, HBP, cor pulmonale, CHD (OR 1.03 [95% CI 1.01–1.05]; p = 0.035), model 4 which was adjusted for the variables in model 3 plus PO2, PCO2, NEU%, HB, platelets, BUN, ALB, creatinine, potassium, and sodium (OR 1.03 [95% CI 1.01–1.07]; p = 0.035). The gene discussed is ALB; the disease is cor pulmonale.
