Adjusted odds ratios for hospital mortality. Model 1 adjusted for age and sex; Model 2 adjusted for age, sex, diabetes mellites, chronic kidney disease, hypertension, white blood cells, serum albumin, serum total bilirubin, and serum ferritin. APRI: Aspartate transferase-to-platelet ratio index; CKD: Chronic kidney disease; CI: Confidence interval; DM: Diabetes mellites; HTN: Hypertension; IQR: Interquartile range; WBCs: White blood cells.
