Multivariate Cox regression analysis was conducted after adjustment for sex, age over 65 years, hypertension, diabetes mellitus, ischemic heart disease, underlying liver disease, chronic kidney disease (eGFR ≤ 60 ml/min/1.73 m²), KDIGO stage 3 AKI, Hb < 11 g/dL, CRP, and albumin.

AKI acute kidney disease, HTN hypertension, DM diabetes mellitus, CKD chronic kidney disease.
