Fig Associations of the baseline ankle-brachial index (ABI) measurement with change in Medical Outcomes Study 36-Item Short Form (SF-36) Physical Component Score (PCS) and Mental Component Score (MCS) over time, as well as summary performance score (SPS) at follow-up. The x-axis denotes the beta coefficients for the models. The dashed black line represents a null value of zero, or no association. The blue circles represent the beta coefficients for unadjusted models, the red triangles represent beta coefficients in models adjusted for age, sex, and race/ethnicity, while the green squares represent beta coefficients for fully adjusted models with age, sex, race/ethnicity, ever smoker, body mass index (BMI), physical activity, diabetes, hypertension and dyslipidemia. The error bars are the 95% confidence intervals (CIs) around the beta coefficients. Journal of Vascular Surgery , e1DOI: ( /j.jvs ) Copyright © 2016 Society for Vascular Surgery Terms and Conditions

Supplementary Fig (online only)
Distribution of the baseline and follow-up ankle brachial indexes (ABIs). A histogram for the ABI at baseline is in gray, overlaid with a histogram of the follow-up ABI in light blue. The x-axis displays the ABI values while the y-axis displays the histogram density. Journal of Vascular Surgery , e1DOI: ( /j.jvs ) Copyright © 2016 Society for Vascular Surgery Terms and Conditions
