Therapeutic success defined as at least 10-point increase of Physical functioning questionnaire (PF-10 ) score after approximately 6 weeks of Spiolto® Respimat® treatment. The PF-10 used for assessing the primary outcome "physical functioning" is a subdomain of the validated Short Form 36 (SF-36 ) and consists of 10 questions evaluating the extent of experienced restrictions while conducting usual activities. Each question of the PF-10 can be answered with "yes, limited a lot", "yes, limited a little" or "no, not limited at all", with a score of 1, 2 or 3. The sum of the scores of the 10 questions results in a value between 10 (a patient answering all questions with "yes, limited a lot") and 30 (a patient answering all questions with "no, not limited at all"). The final sum of the individual scores was standardized to a range of 0 to 100 using the following formula: [(sum of scale items - 10) * 100] / 20.

Higher scores indicate better physical functioning.

Full Analysis Set (FAS): All screened patients with at least one documented administration of Spiolto® Respimat® and available PF-10 score at visit 1 and visit 2.

The change in Physical functioning questionnaire (PF-10 ) score was determined by taking into account the individual change of each patient between Baseline (Visit 1) and Week 6 (approx.) (Visit 2) and then the mean for change from baseline values across all patients was calculated.

The patient's general condition was evaluated by means of Physician's Global Evaluation (PGE) score. The PGE score is documented on a scale from 1 (poor) to 8 (excellent) at both visits. 1-2: poor; 3-4: satisfactory; 5-6: good; 7-8: excellent

FAS

A patient satisfaction questionnaire on how overall satisfied they were with the Spiolto® Respimat® treatment was also completed during visit 2, using a 7-point ordinal scale, from 1 (very unsatisfied) to 7 (very satisfied).

FAS who completed the questionnaire.14 patients with missing data were excluded from the analysis.

A patient satisfaction questionnaire on how satisfied they were by inhaling with the Respimat® device was also completed during visit 2, using a 7-point ordinal scale, from 1 (very unsatisfied) to 7 (very satisfied).
