What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Main Study - The Percentage of Collected Auscultation Points | For each participants the auscultation sound files were collected at 12 points of the body. In each defined region of the participant's body, auscultation was to be performed to maximize the sound quality according to the investigator's experience. Auscultations were recorded using a Littmann Digital Stethoscope (Model 3200) and the 3M Littmann StethAssist software on a computer provided for the study. The unit of the measure is Percentage of auscultation points collected per participants. | Day 1 (Visit 1) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Entire Study - Participants Reported Symptoms of Respiratory Disease - Dyspnoea Recorded Via a Modified Medical Research Council (MRC) Scale | Dyspnoea was assessed for participants as grade 0 and 1 of the modified MRC scale, ranging from 0 to 4 with '0´ being minor and '4´ being severe. Where, 0 = I only get breathless with strenuous exercise; = I get short of breath when hurrying on level ground or walking up a slight hill; = On level ground, I walk slower than people of the same age because of breathlessness, or have to stop for breath when walking at my own pace; = I stop for breath after walking about 100 meters or after a few minutes on level ground; = I am too breathless to leave the house or I am breathless when dressing. | Day 1 (Visit 1) | 
| Entire Study - Participants Reported Symptoms of Respiratory Disease - Cough and Sputum | Number of participants that reported symptoms of respiratory disease (Cough and Sputum) for day time (DT) and night time (NT) is presented. | Day 1 (Visit 1) | 
| Entire Study - Smoking Status | Smoking status is presented as ex-smokers, currently smokers and never smoked participants for main and sub-study combined (entire study). | Day 1 (Visit 1) | 
| Entire Study - Body Mass Index (BMI) | BMI is defined as the body weight divided by the square of the body height is presented for main and sub-study combined (entire study). | Day 1 (Visit 1) | 
| Sub Study - The Percentage of Collected Auscultation Points | For each participants the auscultation sound files were collected at 12 points of the body. In each defined region of the participant's body, auscultation was to be performed to maximize the sound quality according to the investigator's experience. Auscultations were recorded using a Littmann 3200 and the Ekuore One stethoscope. The unit of the measure is Percentage of auscultation points collected per participants. | Day 1 (Visit 1) |
