Fig 1 Population-based amputation rates for peripheral arterial disease (PAD) by hospital referral regions are shown on the map. Journal of Vascular Surgery 2013 57, 1471-1480.e3DOI: (10.1016/j.jvs.2012.11.068) Copyright © 2013 Society for Vascular Surgery Terms and Conditions
Fig 2 Correlation at the regional level is shown between intensity of vascular care and amputation rate. Intensity of vascular care is measured as a function of (A) all inpatient revascularizations, (B) all inpatient open surgical revascularizations, (C) inpatient therapeutic endovascular procedures, and (D) inpatient and outpatient diagnostic and therapeutic, open and endovascular revascularization procedures. *Amputation rates specifies major (above or below) knee amputation rate per 10,000 Medicare beneficiaries. †Intensity of care measured as a function of the number of procedures performed in the year prior to amputation.

Fig 3 A, The mean number of revascularization procedures (therapeutic endovascular interventions or bypass surgery) for each amputation is shown by the quintile of the population-based amputation rate. *P is for nonparametric test of trend across all regions. B, The mean number of other vascular procedures for each amputation is shown by the quintile of the population-based amputation rate.
