In Model 2, we adjusted for Model 1 plus intubation time, BMI, albumin, eGFR < 60 mL/min/1.73 m2, hemoglobin, BNP, transfusion of red blood cells, hemoglobin, and ICU stay and found that sarcopenia (OR 2.507; 95% CI 1.138–5.521, P < 0.05) and intubation time (OR 1.027; 95% CI 1.002–1.053, P < 0.05) were significant factors (Table 3B). The gene discussed is ALB; the disease is sarcopenia.
