Figure 2.

Correlations between changes in FEV₁ following bronchial dilation and baseline FEV₁ and eosinophil count. A total of 129 bronchiectasis patients were included in the analysis. The dotted lines indicated the 95% confidence interval for the correlation. (A) Correlations between baseline FEV₁ predicted and changes in FEV₁ (%); (B) correlations between post-bronchodilator changes in FEV₁ (%) and blood eosinophil percentage (r=0.15, P=0.18); (C) correlations between post-bronchodilator changes in FEV₁ (%) and sputum eosinophil percentage (r=0.07, P=0.64).
