In individual multiple logistic regression models adjusted for age and sex, older age (OR 1.08, 95% CI 1.04–1.13/1 year), lower hemoglobin (OR 0.98, 95% CI 0.95–1.00/1 g/L), higher white blood cell (OR 2.82, 95% CI 1.03–7.76/1 g/L), presence of AKI (OR 6.02, 95% CI 2.10–17.30), and lower serum albumin (OR 0.81, 95% CI 0.72–0.90/1 g/L) were related to all-cause in-hospital mortality. The gene discussed is ALB; the disease is acute kidney injury.
