Univariate analysis of potential predictors of restart of RRT within 90 days

	OR	95% CI	p value
Urinary NGAL (day 2), ng/mL	1.00	1.00–1.00	0.053
Urine output (day 2), L	0.60	0.39–0.92	0.020
Creatinine ratio (day 2/0)	5.15	1.42–18.69	0.013
Non-renal SOFA score (day 2)	0.98	0.84–1.15	0.828
Preadmission eGFR	1.00	0.98–1.02	0.883

The ORs are per unit increase.

NGAL is expressed in ng/mL.

RRT, renal replacement therapy; NGAL, neutrophil gelatinase-associated lipocalin; SOFA, sequential organ failure assessment; eGFR, estimated glomerular filtration rate.
