Abstract
Background In people with lower-extremity peripheral artery disease, the effects of exercise on patient-reported outcomes remain unclear. Methods and Results Four hundred four people with peripheral artery disease in 3 clinical trials were randomized to exercise (N=205) or a control group (N=199) and completed the 6-minute walk and the Walking Impairment Questionnaire distance score (score 0-100, 100=best) at baseline and 6-month follow-up. Compared with the control group, exercise improved 6-minute walk distance by +39.8 m (95% CI, 26.8-52.8, P
