What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

• SpirometryProcedure or surgery

  Classification of respiratory diseases by Spirometry will be performed to differentiate subjects between Asthma only, ACOS, and COPD only. Spirometry obtained from measurements in the past 6 months is acceptable for purposes of this study. For subjects without spirometry in the past 6 months, spirometry will be performed to obtain pre- and post-bronchodilator Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC) and reversibility

• ACOS clinical questionnaireOther

  The 41-question questionnaire includes questions concerning the following: a) response to bronchodilator, b) disease progression, c) variations in symptom, d) atopic history, e) symptom triggers, f) vagal bias, g) burden of disease, h) symptom presentation, i) emotional aspects, and j) age of onset. In addition, two questions will capture patient perception of his/her respiratory disease and the physician's diagnosis

What is being measured

The primary outcome is the main question the study is designed to answer.

1. Summary of spirometry data: forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)

   FEV1 measures how much air a person can exhale during a forced breath in 1 second. FVC is the total amount of air exhaled during the FEV test. FEV1 and FVC were performed on Day 1 (pre- and post-bronchodilator) using spirometry. Spirometry results obtained within 6 months and were used for this study. For participants without spirometry in the past 6 months, spirometry was performed to obtain pre- and post-bronchodilator FEV1, FVC.

   Measured: Day 1

2. Summary of spirometry data: Reversibility

   Questionnaire designed to clinically differentiate participants with ACOS from patients who have either asthma alone (i.e. without persistent obstruction) or COPD alone (i.e., non-reversible). Spirometry results obtained within 6 months and were used for this study. For participants without spirometry in the past 6 months, spirometry was performed to obtain pre- and post-bronchodilator FEV1, FVC and reversibility.

   Measured: Day 1

3. Number of participants with response to Bronchodilators (Questionnaire Items 1 and 2)

   ACOS Medical history questionnaire is a disease specific (asthma and/or COPD) questionnaire administered by a qualified health care practitioner to assess the clinical features of asthma and/or COPD. Items were grouped in 10 different domains. Response to bronchodilators was one domain in which, participants had to answer questions (Q)1-2 (Q1: How well does your participant's quick relief inhaler (rescue inhaler) provide symptom relief? and Q2: How often does the participant need to keep a rescue inhaler with him/her?) regarding rescue inhaler and need to keep inhaler with participants Responses were recorded as No relief, Relief and No need, Need. Number of participants with such responses were recorded.

   Measured: Day 1
