The AKIN classification was based on serum creatinine values and renal replacement therapy.. Urine output criteria were ignored. The RIFLE classification was based on serum creatinine values. Urine output criteria were ignored. aNumber of evaluable patients (those for whom a score could be determined); bnumber of patients analysed; cpercentages based on the number of evaluable patients; AKIN, Acute Kidney Injury Network; RIFLE, risk, injury, failure, loss, end-stage kidney disease; HES, hydroxyethyl starch; NaCI, sodium chloride.
