TABLE 2.

Univariable and multivariable logistic regression analyses of associations between a body shape index (ABSI) and abdominal aortic calcification (AAC).

	ABSI as a continuous variablea			ABSI as a categorical variableb
	OR	95% CI	P value	OR	95% CI	P value
Crude model	2.485	2.099–2.942	< 0.001	2.132	1.826–2.489	< 0.001
Model 1	1.378	1.150–1.653	0.001	1.257	1.057–1.494	0.010
Model 2	1.287	1.070–1.547	0.007	1.220	1.025–1.453	0.025
Model 3	1.259	1.046–1.516	0.015	1.201	1.008–1.430	0.041

Crude model: unadjusted.

Model 1: adjusted for age, smoking history, hypertension, diabetes, and osteoporosis.

Model 2: adjusted for variables included in Model 1 and body mass index, systolic blood pressure.

Model 3: adjusted for variables included in Model 2 and triglycerides, total cholesterol, creatinine, and fasting plasma glucose.

ABSI, a body shape index; AAC, abdominal aortic calcification; OR, odds ratio; CI, confidence interval.

^aThe OR was examined by per 1-unit increase of ABSI.

^bThe OR was examined regarding lower ABSI as reference (stratified by the optimal cutoff point of ABSI determined by ROC curve analysis).
