1Pre- and post-bronchodilator spirometry will be obtained at baseline visit 1 to determine reversibility of airway obstruction, which is an eligibility criterion. Only pre-bronchodilator spirometry will be performed at baseline visit 2 and at 6- and 12-month assessments and the measurements obtained will be used for analysis.

2Data will be extracted for a period of 12 months before and after randomization.

Abbreviations: ERV, expiratory reserve volume; FEV1, forced expiratory volume in one second; FEV6, forced expiratory volume in six seconds; FVC, forced vital capacity; IC, inspiratory capacity; KPNC, Kaiser Permanente in Northern California; VCin and VCex, inspiratory and expiratory vital capacity; VT, tidal volume.
