Table 2. Multivariate logistic regression model using HDL-C quartile levels for predicting CI-AKI.

Variables	OR	95% CI	P value	P for trend
History of CVA	2.023	1.142–3.587	0.016
LVEF	0.960	0.945–0.975	<0.001
Non-HDL-C	1.006	1.001–1.010	0.013
Pre-procedural HDL-C quartile 1			<0.001	<0.001
Pre-procedural HDL-C quartile 2	0.716	0.421–1.219	0.219
Pre-procedural HDL-C quartile 3	0.534	0.301–0.947	0.032
Pre-procedural HDL-C quartile 4	0.173	0.079–0.377	<0.001
Pre-procedural MDRD eGFR	0.978	0.963–0.993	0.004

*Adjusted for age, BMI, DM, hypertension, history of CVA, LVEF, hemoglobin, albumin, pre-procedural plasma glucose, HDL and non-HDL cholesterol, uric acid, phosphorus, pre-procedural MDRD eGFR and UPCR. P for trend refers to a linear trend across the lowest to highest quartile. Pre-procedural HDL quartile 1: <34 mg/dl, quartile 2: <40 mg/dl, quartile 3: <48 mg/dl, quartile 4: ≥48 mg/dl. HDL-C, high density lipoprotein cholesterol; CI-AKI, contrast-induced acute kidney injury; OR, odds ratio; CI, confidence interval; CVA, cerebrovascular accident; LVEF, left ventricular ejection fraction; MDRD eGFR, Modification of Diet in Renal Disease estimated glomerular filtration rate.
