Binary logistic regression analysis in predicting nonrecovery of renal function from AKI in critically ill patients (backward method)

Parameters	OR	95% CI	P
Urinary NGAL	1.015	1.000–1.006	0.018
Urinary L-FABP	1.003	1.000–1.030	0.006
RIFLE (failure)	14.8	2.250–97.060	0.001

Excluded variables: acidosis, age, hemoglobin, intra-abdominal hypertension, intra-abdominal pressure on admission, ileus, polytransfusion, Simplified Acute Physiology Score II, sepsis, and shock.

AKI, acute kidney injury; CI, confidence interval; L-FABP, liver-type fatty acid binding protein; NGAL, neutrophil gelatinase-associated lipocalin; OR, odds ratio; RIFLE, risk–injury–failure–loss–end-stage kidney disease.
