Contrast Medium Induced Nephropathy after Endovascular Stent Graft Placement: An Examination of Its Prevalence and Risk Factors

Table 4

Factors associated with the development of CIN.

	Odds ratio	value	95% CI
Aged 80 years or older	7.80	0.026	1.28–47.4
Left ventricular dysfunction	9.34	0.018	1.46–59.7

CIN: contrast-induced nephropathy; CI: confidence interval. Note that left ventricular dysfunction was defined as an ejection fraction of 30% or lower.
