Male	2.56	1.79–3.67	<0.001
Race
African American vs. White	1.89	1.12–3.19	0.02

Hypertension	0.68	0.43–1.09	0.11
Cardiac disease	0.76	0.39–1.48	0.42
APS-III score,a by units of 10	1.18	1.09–1.29	<0.001
Weight-adjusted urine output,a,b by 100 ml	0.98	0.97–0.99	<0.001

AKD, acute kidney disease; aOR, adjusted odds ratio; APS-III, Acute Physiology Score III; CI, confidence interval.

N = 476; area under the receiver operating characteristic curve = 0.71 (95% CI, 0.66–0.76); goodness-of-fit P value = 0.49.

^aSquare-root transformation was used for selected variables in the model.

^bThe available urine volume in the 24 hours after intensive-care unit admission was summed and divided by the weight.

^cCaptured in 6 hours after randomization.
