Why this national study?
Earlier Jordanian figures reveal a gap we cannot ignore.
Knew that COPD was a smoking-related respiratory illness in that same community study.
Research source ↗Of COPD cases were previously undiagnosed in a later high-risk clinical sample of Jordanian male smokers.
Research source ↗⚑ These figures come from specific samples—not national estimates. That limitation is exactly why a representative national lung-function dataset is needed.
Who is invited?
Field teams reached households through the approved sampling plan, then checked eligibility among adults aged 18 years and older. Participation was not open enrolment through this website.
