Fig 1 Flow diagram of the study and data collection. PAD, peripheral artery disease; MRA, magnetic resonance angiography; CTA, computed tomographic angiography; ABPI, ankle brachial pressure index. *DSA, digital subtraction angiography. **PTA, percutaneous transluminal angioplasty. †After follow-up, 386 patients returned their questionnaire. The percentages are calculated using these 386 patients. Journal of Vascular Surgery , DOI: ( /j.jvs ) Copyright © 2005 The Society for Vascular Surgery Terms and Conditions

Fig 2 Receiver operating characteristic (ROC) curve at baseline for patients with claudication. P 1–2 = .6, (P value comparing AUCs VascuQol with SF-36). P 1–3 = .8, (P value comparing AUCs VascuQol with EuroQol-5D). P 2–3 = .8; (P-value comparing AUCs SF-36 with EuroQol-5D).
