Urinary Hepcidin-25 is Independently Associated with AKI on Multivariate Analysis.

Characteristic	Odds ratio	95% confidence interval	P value
Baseline eGFR (per mL/min/1.73 m2)	0.96	0.95-0.98	<.01
Diabetes mellitus act	3.08	1.47-6.45	<.01
Urine hepcidin-25 (per 1000 ng/mL)	0.67	0.50-0.95	.02

Note. Final multivariable logistic regression model developed using stepwise selection method. Missing covariate values estimated via multiple imputation. Outcome: AKI defined as Cr > 50% from baseline or a ≥26.5 μmol/L within 48 hours. Area under the ROC curve = 0.82 (0.75-0.88). Hosmer-Lemeshow P value = .90. AKI = acute kidney injury; Cr = creatinine; ROC = receiver operating characteristic; eGFR, estimated glomerular filtration rate.
