Influence of urine output and serum creatinine criteria for AKI-2 on outcomes

Criteria met	N (%)	Progressed to RRT, N(%)	Prolonged ICU LOS, N(%)	2-year mortality, N(%)
Urine output alone	97 (43.7)	11 (11.3)	58 (61.1)	10 (10.3)
Creatinine alone	92 (41.4)	30 (32.6) *	70 (79.5)*	15 (16.3)
Urine output AND Creatinine	33 (14.9)	20 (60.6) *†	30 (97.0)* †	9 (27.3)*

AKI acute kidney injury, RRT renal replacement therapy, LOS length of stay
