Summary
This study looked at 1000 adults with a long-term dry cough that might be cough-variant asthma. Researchers measured a breath marker called FeNO to see if it could predict who would feel better after 8 weeks of treatment with a common asthma inhaler (budesonide-formoterol). The goal was to find a cutoff value that helps doctors decide which patients are most likely to benefit from this medicine.
