The purpoe of this study is to determine the relationship between computerized tomography (CT)-defined small airway abnormality (SAA) and disease progression in early chronic obstructive pulmonary disease (COPD), our primary analysis will use linear mixed effects models to estimate and perform inference on trajectories of parametric response mapping emphysema (PRMEmph), based on PRMfSAD (functional small airway disease) and PRMEmph at baseline CT imaging.

The goals of this study are to collect and store biospecimens (e.g., blood, urine, saliva, stool) in order to support future research. These biospecimens will be tested and used to better understand why a disease or disorder occurs and how it progresses over time. This knowledge could aid future patients.
