Influence of urine output and serum creatinine criteria for AKI-1 on outcomes

Criteria met	N (%)	Progressed to RRT, N(%)	Prolonged LOS N(%)	2-year mortality, N(%)
Urine output alone	370 (47.9)	16 (4.3)	145 (39.6)	22 (5.9)
Creatinine alone	192 (24.9)	28 (14.6) *	119 (64.7)*	24 (12.5)*
Urine output AND Creatinine	210 (27.2)	58 (27.6) *†	155 (76.0)* †	39 (18.6)*
