Anne V. Gonzalez, M.D., from the McGill University Health Centre in Montreal, and colleagues used data from Quebec health care databases to identify a cohort of patients with COPD from 1990 to 2005 who were followed until 2007 for the first hip or upper extremity fracture. Each fracture case was matched with 20 controls by age, sex, and follow-up time as part of a nested case-control analysis.
