Outcome Measures
Primary Outcomes (1)
Change in pulmonary function over time by arm of study
Outcome is assessed at annual and bi-annual study visits, during in-person visit of participant to the study site. Over a period of about 36 to 48 months, participants are assessed between 3 and 4 times
Other Outcomes (1)
Effect of selenium and vitamin E supplementation on incidence of COPD
Questionnaire data on incident lung disease is assessed at annual and biannual study visits, in all SELECT participants. These questionnaire data were collected through the end of SELECT active follow-up, which was December 2010
