Fig 1 Distribution of body mass index (BMI). This histogram shows the frequency of BMI found throughout the study population. The number over each bar is the number of patients with that BMI. The mean BMI is 27 ± 6 kg/m2. Journal of Vascular Surgery 2007 46, 738-742DOI: (10.1016/j.jvs.2007.05.044) Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

Fig 2 Kaplan-Meier curves plotting the fraction of the study population alive over time. The solid line represents survival in nonobese patients, and the dashed line represents the survival of obese patients. Arrows delineate where the standard deviation of the curve exceeds 10%.

Fig 3 Kaplan-Meier curves plotting the fraction of graft patency over time. The solid line represents graft patency in the nonobese group, and the dashed line represents graft patency in obese patients. Arrows delineate where the standard deviation of the curve exceeds 10%.

Fig 4 Amputation-free survival. Kaplan-Meier curves plotting the fraction of patients undergoing major amputation over time. The solid line represents freedom from amputation in the nonobese group, and the dashed line represents freedom from amputation in obese patients. BMI, Body mass index.
