	β^b ± Standard Error	P
Unadjusted	−19.0 ± 5.2	<.001
Model 1^c	−11.9 ± 5.4	.038
Model 2^d	−13.9 ± 5.9	.020
Model 3^e	−11.6 ± 5.9	.049

Abbreviations: NT-pro-BNP, N-terminal pro-B-type natriuretic peptide; eGFR, estimated glomerular filtration rate.

352 patients underwent the treadmill test.

The β coefficients represent the predicted response (walking capacity in yards) for a 1 unit change in log NT-pro-BNP level.

Model 1: adjusted for age, sex, and body mass index (BMI).

Model 2: adjusted for age, sex, BMI, smoking status, presence of diabetes, hypertension, dyslipidemia, coronary heart disease/cerebrovascular disease, eGFR, statin use, and pulse pressure.

Model 3: adjusted for variables in model 2 plus resting ankle–brachial index.
