Multiple logistic regression model for AKI risk

Variables	OR	CI	P Value
pNGAL low-/no-risk category
pNGAL in gray zone	4.4	2.3 to 8.6	<0.001
pNGAL high-risk category	9.8	5.6 to 16.9	<0.001
Age (yr)	1.1	1.0 to 1.2	0.04
CVD	2.20	1.3 to 3.7	0.003
Susceptibility	3.80	2.0 to 7.0	<0.001

Plasma neutrophil gelatinase-associated lipocalin (pNGAL) at 12 hours at low risk (<97 ng/ml), gray zone (97–133 ng/ml), and high risk (>133 ng/ml) analyzed together with the clinical variables: age, cardiovascular disease (CVD), and susceptibility. OR, odds ratio; CI, 95% confidence interval.
