^cThese measures were performed at baseline visit unless patient was experiencing an exacerbation or feeling too ill during their baseline enrollment visit, in which case they were performed when the patient was deemed in a stable state. Forced Expiratory Volume in 1 Second (FEV1) was measured via portable spirometry.
