Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We aimed to collect clinical and radiological data of patients with stable COPD in plateau and plain, and compare the clinical phenotypic characteristics and imaging features of COPD patients in these two areas.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study was to investigate the clinical phenotypic characteristics and imaging features of patients with stable chronic obstructive pulmonary disease (COPD) in plateau and plain. We conducted a cross-sectional study, collecting clinical data of stable patients in plateau and plain, and comparing the clinical phenotypic characteristics and imaging features of COPD patients in these two areas.
