Association Between Blood Eosinophils and Neutrophils With Clinical Features in Adult-Onset Asthma.

Background: Asthma is a disease that can be separated into different phenotypes and endotypes based on the clinical characteristics and the molecular mechanisms of the condition, respectively.

Objective: To assess the association between blood eosinophil and neutrophil counts with clinical and molecular features in patients with adult-onset asthma.
