Percent of Predicted Bronchodilator Effect of Indacaterol Salts Compared to Placebo Measured by FEV1 (% Predicted) at All Timepoints	The FEV1 percent predicted expresses FEV1 as a percentage of the "predicted values" for participants of similar characteristics (height, age, sex, and sometimes race and weight). A positive change from baseline in FEV1 % predicted indicates improvement in lung function. FEV1 % predicted was assessed at each post dose time point after 14 days	Day 14 of each of the three treatment periods at 5, 15, 30m, 1 2, 3, 4, 8, 12, 23hour.15min and 23hour.45min
Bronchodilator Effect of Indacaterol Salts Compared to Placebo Measured by Forced Vital Capacity (FVC)	Forced Vital Capacity is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. FVC was assessed by spirometry at each post dose time point after 14 days. A positive change from baseline in FVC indicates improvement in lung function.	Day 14 of each of the three treatment periods at at 5, 15, 30m, 1 2, 3, 4, 8, 12, 23hour.15min and 23hour.45min
Bronchodilator Effect of Indacaterol Salts Compared to Placebo Measured by FVC (% Predicted)	Forced Vital Capacity is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. FVC was assessed by spirometry at each post dose time point after 14 days. A positive change from baseline in FVC indicates improvement in lung function.

FEV1/FVC ratio is the percentage of the total FVC that is expelled from the lungs during the first second of forced exhalation.	Day 14 of each of the three treatment periods at 5, 15, 30m, 1 2, 3, 4, 8, 12, 23hour.15min and 23hour.45min
Bronchodilator Effect of Indacaterol Salts Compared to Placebo Measured by FEF25-75%	The Forced Expiratory Flow (FEF) 25%-75% measurement describes the amount of air expelled from the lungs during the middle half (25% - 75%) of the forced vital capacity test and is measured using spirometry at each post dose time point after 14 days	Day 14 of each of the three treatment periods at 5, 15, 30m, 1 2, 3, 4, 8, 12, 23hour.15min and 23hour.45min
Bronchodilator Effect of Indacaterol Salts Compared to Placebo in Standardized FEV1 AUC.	Standardized FEV1 AUC from pre-dose to 4 h post-dose. Evaluated the differences in standardized FEV1 AUC0-4h (L) after 14 days of treatment between indacaterol maleate 150 μg and placebo, and between indacaterol acetate 150 μg and placebo. FEV1 was measured with spirometry conducted according to internationally accepted standards. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time over an entire day (AUC 0-4h)	Pre-dose to 4 hours post-dose on Day 14 of each of the three treatment periods
Rescue Medication Usage	The mean daily number of puffs of rescue medication usage as reported by subjects via diary.	14 days of treatment for each of the three treatment periods
Mean Overall Peak Expiratory Flow (PEF)	A Peak Expiratory Flow (PEF) meter was distributed to patients at Visit 1, to be used to measure PEF twice-daily as directed. During the Screening and Treatment Periods, PEF was measured in the morning and evening every day. the morning PEF was performed within 15 minutes after waking, and the evening PEF approximately 12 hours later. The highest of 3 values was recorded as the daily personal best. The personal best was used to calculate the mean morning PEF and mean evening PEF value collected between assessment Visits LS Mean of change from baseline in mean morning PEF is calculated with the ANOVA model using treatment, stratification group, dosing schedule, gender, center grouping, smoking status, and baseline mean morning PEF as covariates	Days 8 through Day 14 of each of the three treatment periods
