Chronic obstructive pulmonary disease (COPD), a heterogeneous disease, is a leading cause of high morbidity and mortality.1,2 In patients with COPD, predictive factors, such as acute exacerbation, lung function decline, and death are very important because they are closely related to prognosis. Because these risk factors are different for each COPD patients, it is necessary to analyze clinical phenotypes and subgroups for tailored precision treatment. Therefore, many studies have been conducted to analyze these clinical phenotypes of COPD and to develop biomarkers that can represent each phenotype.
