Participant flow

Recruitment details

This study was conducted in a total of 119 enrolling sites: 72 sites in the United States, 13 sites in Argentina, 13 sites in Australia, 7 sites in Canada, 2 sites in Mexico, 3 sites in New Zealand and 9 sites in South Africa. The first patient was screened in August 2006 and the last patient visit was in June 2008.

Pre-assignment details

Following a screening visit, patients entered a 14-day run-in period during which they used inhaled salbutamol on an as needed basis. Patients also stopped taking any other COPD medications prohibited by the study protocol. The 14-day run-in period was used to assess the stability of disease and established the patient's baseline characteristics.
