  • 1

    Higher eosinophil counts correlate with less bronchial thickening.

  • 2

    Study involved 448 COPD patients, primarily men with mean age 68.

  • 3

    Eosinophil thresholds: 2%, 150/µL, 300/µL benefitted lung function.

  • 4

    Emphysema index reduced at eosinophil count ≥300/µL.

  • 5

    Limitations included a small sample size and cross-sectional analysis.

  • 6

    Eosinophil levels inform inhaled corticosteroid decisions in COPD treatment.

  • 7

    QCT may enhance interpretation of eosinophil strata in clinical practice.
