Distinct asthma phenotypes with low maximal attainment of lung function on cluster analysis.

Asthma is a heterogeneous disease with varying clinical presentations, severity and ability to achieve asthma control. The present study aimed to characterize clinical phenotypes of asthma in an Indian cohort of subjects using a cluster analysis approach. Patients with confirmed asthma ( Cluster analysis of 100 treatment-naive patients with asthma identified four clusters. Cluster 1, ( In an Indian cohort of well-characterized patients with asthma, cluster analysis identified four distinct clinical phenotypes of asthma, two of which had poor attainment of maximum lung functions.
