Errors in Table. In the Original Contribution entitled “Treadmill Exercise and Resistance Training in Patients With Peripheral Arterial Disease With and Without Intermittent Claudication: A Randomized Trial,” published in the January 14, 2009, issue of JAMA (2009;301[2]:165-174), data in the “Intermittent claudication” row of Table 1 were incorrect. The number (%) for the treadmill walking exercise group should have read “18 (35.3)”; for the lower extremity resistance training group, “18 (34.6)”; for the control group, “20 (37.7)”; and for the P value, “.94.”
