Changes in St. George's Respiratory Questionnaire for COPD Patients Score
Временное ограничение: 3, 6, 9, and 12 months after baseline
|
The St. George's Respiratory Questionnaire for COPD patients (SGRQ-C) score ranges from 0 to 100.
Higher scores indicate a worse outcome (poorer health-related quality of life).
|
3, 6, 9, and 12 months after baseline
|
|
Changes in EuroQol 5-Dimension 5-Level Score
Временное ограничение: 3, 6, 9, and 12 months after baseline
|
The EuroQol 5-Dimension 5-Level (EQ-5D-5L) score consists of two parts: a questionnaire and a visual analogue scale (VAS).
The questionnaire includes five dimensions, where higher scores indicate worse health status.
The VAS asks respondents to rate their overall health status on a 0-100 scale.
Higher scores on the VAS mean a better outcome (better self-rated health status).

3, 6, 9, and 12 months after baseline
|
|
Change from Baseline in Forced Expiratory Volume in 1 Second
Временное ограничение: 6 and 12 months after baseline
|
Forced Expiratory Volume in 1 Second (FEV1) will be measured in liters using spirometry.
|
6 and 12 months after baseline
|
|
Change from Baseline in Forced Vital Capacity
Временное ограничение: 6 and 12 months after baseline
|
Forced Vital Capacity (FVC) will be measured in liters using spirometry.
|
6 and 12 months after baseline
|
|
Change from Baseline in Percent Predicted FEV1
Временное ограничение: 6 and 12 months after baseline
|
Percent Predicted Forced Expiratory Volume in 1 Second (FEV1%pred) will be calculated from spirometry and expressed as a percentage of the predicted value.
|
6 and 12 months after baseline
|
|

|
|
Changes in Environmental Temperature Risk Perception Score
Временное ограничение: 3, 6, 9, and 12 months after baseline
|
Used to assess the participant's awareness and perception of health risks related to environmental temperature on the basis of the Temperature Risk Perception Questionnaire.

|
|
Number of Participants With Abnormal Complete Blood Count Results
Временное ограничение: 12 months after baseline
|
Abnormal complete blood count (CBC) readings will be identified from standard clinical CBC reports by qualified physicians.
The total number of participants with these abnormal readings will be counted.
A lower number of participants with abnormal CBC readings means a better outcome (better clinical safety profile).
|
