Lung function tests consisted of 3 forced expiratory maneuvers in which the patient expired forcefully from total lung capacity to residual volume, recorded using a spirometer. SVC is the measure of the change in volume of gas in the lungs from complete inspiration to complete expiration.

The efficacy analysis set included all patients who were randomized (defined as having a randomization code recorded on the demography case report form), received at least one dose of study medication, and contributed sufficient data for at least one efficacy endpoint.

Lung function tests consisted of 3 forced expiratory maneuvers in which the patient expired forcefully from total lung capacity to residual volume, recorded using a spirometer. FVC is the maximum volume of air which can be exhaled or inspired during a forced maneuver.

Lung function tests consisted of 3 forced expiratory maneuvers in which the patient expired forcefully from total lung capacity to residual volume, recorded using a spirometer. FEF25-75 is flow rate during the middle half of forced vital capacity (25%-75% of the total volume (FVC) exhaled).

TDI measures changes in dyspnea severity from the baseline as established by the Baseline Dyspnea Index (BDI). TDI is an interviewer-administered rating of severity of dyspnea that assesses Change in Functional Impairment, Change in Magnitude of Task, and Change in Magnitude of Effort domains on a 7-point scale ranging from -3 (major deterioration) to +3 (major improvement). Total score ranges from -9 to +9. The lower the score, the more deterioration in severity of dyspnea.

The efficacy analysis set included all patients who were randomized (defined as having a randomization code recorded on the demography case report form), received at least one dose of study medication, and contributed sufficient data for at least one efficacy endpoint.

The Bronkotest diary card is a paper based diary card that was filled out by patients daily, recording values from morning and evening peak expiratory flow (PEF) measurements and answering 8 questions on signs and symptoms. Summary statistics for baseline (mean of the last 7 days prior to first dose) and change (mean of the last 7 days on treatment - baseline) only contain patients included in the analysis. For symptom scores a decrease is an improvement, for PEF an increase is an improvement.

The Bronkotest diary card is a paper based diary card that was filled out by patients daily, recording values from morning and evening peak expiratory flow (PEF) measurements and answering 8 questions on signs and symptoms. Symptom scores were recorded for night-time symptoms, breathing, sputum colour, sputum amount, sputum type, wellbeing, number of puffs of inhalers, and cough, generally scored on a scale from 0 (no symptoms) to 4 (worst symptoms). Summary statistics for baseline (mean of the last 7 days prior to first dose) and change (mean of the last 7 days on treatment - baseline) only contain patients included in the analysis. For symptom scores a decrease is an improvement, for PEF an increase is an improvement.

The efficacy analysis set included all patients who were randomized (defined as having a randomization code recorded on the demography case report form), received at least one dose of study medication, and contributed sufficient data for at least one efficacy endpoint.

SGRQ-C total score shows the impact of COPD on patient's health status, and expressed as a percentage of impairment with scale from 0 (best health status) to 100 (worst possible status). The SGRQ-C contains 3 domains:

Symptom (distress due to respiratory symptoms), Activity (disturbance of physical activity) and Impact (overall impact on daily life and well being). All three domains with scale from 0 (best health status) to 100 (worst possible status).

The efficacy analysis set included all patients who were randomized (defined as having a randomization code recorded on the demography case report form), received at least one dose of study medication, and contributed sufficient data for at least one efficacy endpoint.
