Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Prevalence of Previously Diagnosed Chronic Obstructive Pulmonary Disease | Study period: October 24, 2024-September 20, 2026. Outcome Time Frame: "Baseline (Day 1, at the single survey assessment)." | Percentage of participants reporting a previous clinical diagnosis of chronic obstructive pulmonary disease, based on questionnaire responses and available medical records. Prevalence is calculated by dividing the number of participants with a previous diagnosis by the total number assessed and multiplying by 100, with a 95% confidence interval. No spirometric confirmation is performed. |
| Secondary | Associations Between Potential Risk Factors and Previously Diagnosed COPD | Study period: October 24, 2024-September 20, 2026. Outcome Time Frame: "Baseline (Day 1, at the single survey assessment)." | Associations between previously diagnosed COPD and demographic characteristics, smoking history, secondhand smoke, occupational and environmental exposures, biofuel and incense use, socioeconomic status, and respiratory medical history, assessed using chi-square tests. |
