Trial overview
Official title: An evaluation of the prevalence of airway obstruction consistent with chronic obstructive pulmonary disease (COPD) in subjects with a history of cigarette smoking and symptoms of chronic bronchitis in a primary care setting
Trial description: The study does not involve testing of a drug (no treatment intervention). The study will will use spirometry (breathing tests) in subjects of 40 years of age and older with a history of cigarette smoking with chronic bronchitis to check their disease status and whether or not they have COPD. Also, study subjects will be asked to complete a questionnaire (to answer a list of questions on paper).
