Summary
This study looked at 502 adults with chronic cough to see if three simple tests (FeNO, blood eosinophils, and total IgE) can predict who will respond to inhaled corticosteroids. Participants took the steroid treatment for 4 weeks, and researchers measured changes in cough severity. The goal was to find a way to personalize treatment and avoid unnecessary medication.
