Figure 3 Comparison of (A) airway wall area percentage (WA%), (B) prominence of centrilobular structure, and (C) air trapping on HRCT scans between patients with eosinophilic bronchitis (EB), mild asthma, and normal controls. WA% was higher in patients with asthma than in those with EB or normal controls (A). The prominence of the centrilobular structure was higher in patients with EB than in those with asthma, but the difference was not statistically significant (p>0.05) (B). Air trapping was higher in patients with asthma than in those with EB, but there was no statistical difference (p>0.05). Patients with EB and those with asthma had greater air trapping than normal controls (C). Bar represents mean (SE). *p = 0.032 v subjects with EB and normal controls; **p<0.05 v normal controls.
