Incorrect Description of Collaborating Hospitals: In the Preliminary Communication entitled “Effect of Folate and Mecobalamin on Hip Fractures in Patients With Stroke: A Randomized Controlled Trial” published in the March 2, 2005, issue of JAMA (2005;293:1082-1088), there was an incorrect description of the hospitals that collaborated in the study. The authors incorrectly stated that the study was performed in a single hospital (Futase Social Insurance Hospital). There were actually 3 additional collaborating hospitals, studying 205, 211, and 159 patients, respectively. The remaining 53 patients were from Futase Social Insurance Hospital, for a total of 628 patients.
