Abstract excerpt

BACKGROUND: Eosinophils in induced sputum are not only a useful biomarker for diagnosing asthma but are also associated with severe asthma. However, little is known about the association between eosinophils in spontaneous sputum and asthma severity. OBJECTIVE: To investigate whether spontaneous sputum eosinophils are related to severe asthma in adult patients with asthma. METHODS: We conducted a retrospective...
