 This study found that copped can be divided into four distinct groups based on the levels of certain biomarkers. The first group had low levels of biomarkers and showed better lung function, while the second group had high levels of biomarkers and showed poorer lung function. Additionally, the third and fourth groups had intermediate levels of biomarkers and showed intermediate lung function. Furthermore, the study also found that the first group had better health outcomes than the other three groups, including fewer comorbidities, less osteoporosis, and less static hyperinflation.
