Spirometry (pre-and post post bronchodilator test), tests of pulmonary function (PFT), cardio pulmonary exercise testing (CPET), a six minute walk test, a multi detector CT scan (MDCT), and a COPD assessment test were completed. A blood sample was collected. Health care utilization (including use of medications), health outcomes and mortality information was collected using provincial health care administrative and vital statistic databases.
