Asthma is a heterogeneous airway disease with various clinical phenotypes. It is crucial to clearly identify clinical phenotypes to achieve better asthma management.We used cluster analysis to classify the clinical groups of 724 asthmatic patients from the Korean Cohort for Reality and Evolution of adult Asthma (COREA), and in 1843 subjects from another independent Korean asthma cohort of Soonchunhyang University Hospitals (SCH cohort). Hierarchical cluster analysis was performed by Ward's method, followed by k-means cluster analysis.Cluster analysis of the COREA cohort indicated four asthma subtypes: (i) smoking asthma, (ii) severe obstructive asthma, (iii) early-onset atopic asthma, and (iv) late-onset mild asthma. An independent cluster analysis of the SCH cohort also indicated four clusters that were similar to the COREA clusters.Our results indicate that adult Korean asthma patients can be classified into four distinct clusters.
