Association of serum myeloperoxidase (MPO) with peripheral arterial disease (PAD): logistic regression models

	African-Americans			Non-Hispanic white individuals
	Odds ratio	95% CI	p	Odds ratio	95% CI	p
Model 1	1.15	0.99–1.34	0.066	1.64	1.19–2.25	0.002
Model 2	1.26	1.07–1.48	0.005	1.48	1.08–2.05	0.016
Model 3	1.24	1.05–1.47	0.010	1.54	1.08–2.19	0.018
Model 4	1.12	0.94–1.34	0.193	1.52	1.06–2.18	0.022

Odds ratios are shown for 1 standard deviation increase in log MPO.

PAD was defined as ABI < 0.9 or >1.4.

Model 1: Unadjusted.

Model 2: Adjusted for age and sex.

Model 3: Adjusted for age, sex, smoking, diabetes, hypertension, estrogen use, waist circumference, total and HDL cholesterol, and statin use.

Model 4: Adjusted for Model 3 variables and C-reactive protein.
