Discussion

Analysis evaluates FeNO and eosinophil levels for diagnosing airway inflammation in AECOPD patients, suggesting clinical importance.

FeNO and peripheral blood eosinophil levels effectively predict airway inflammation in AECOPD patients.
Optimal cut-off values for FeNO, peripheral blood eosinophil count, and percentage were determined to enhance diagnostic accuracy.
The study included 119 patients, revealing significant correlations between eosinophil metrics and airway inflammation.
Findings support the utility of FeNO and eosinophil counts in clinical assessments of airway eosinophilic inflammation.

Zhang et al. (2025) studied this question.
