BSA= Body surface area, BMI= Body Mass Index, CIA= Common iliac artery, EIA= External iliac artery, ABI= Ankle-Brachial index, COT= Claudication onset time on the graded treadmill test, PWT= Peak walking time on the graded treadmill test. The total number of subjects was 39. The numbers less than 39 indicate the missing data for the arterial segments not intervened
