*Creatinine change (%) = [(creatinine at nephrology discharge - Basal creatinine)/Basal creatinine] × 100
^†Creatinine change (%) = [(creatinine at hospital consultation - Basal creatinine)/Basal creatinine] × 100
^‡Adjusted for age, sex, Liano scoring, Karnofsky scoring, prior food intake, chronic renal failure, diabetes, treatment of acute renal failure, causes of acute renal failure, community-acquired acute renal failure, basal hemoglobin, basal serum albumin, and RIFLE classes.
