Clinical features and 1-year outcomes of variable obstruction in participants with preserved spirometry: results from the ECOPD study in China.

ABSTRACT:

Background

There are limited data on the clinical features and longitudinal prognosis of variable obstruction, particularly among never smokers and different variable obstruction types. Therefore, we aimed to evaluate the clinical characteristics of the participants with variable obstruction and determine the relationship between variable obstruction and the development of chronic obstructive pulmonary disease (COPD) and the decline of lung function in a community-dwelling study of Chinese, especially among never smokers and different variable obstruction subtypes.

Methods

Participants with preserved spirometry (postbronchodilator forced expiratory volume in 1 s (FEV₁)/forced vital capacity (FVC) ≥0.70) at baseline from the Early COPD cohort were included in our a
