Figure 1: Box plot showing the bronchial wall thickening and expiratory air trapping score in asthma and chronic obstructive pulmonary disease categorized by severity assessed by forced expiratory volume in one second (a and b) and residual volume/total lung capacity ratio (c and d). The right upper lobe-lumen area/body surface area, right upper lobe-wall area/body surface area, and right upper lobe-total area/body surface area in both groups plotted in forced expiratory volume in one second and residual volume/total lung capacity categorization are shown in (e-h). *P < 0.05 asthma with forced expiratory volume in one second of ≤60% predicted versus asthma with forced expiratory volume in one second of >60% predicted, and asthma with a residual volume/total lung capacity ratio of >40% versus asthma with a residual volume/total lung capacity ratio of ≤40. **P < 0.05 asthma with a residual volume/total lung capacity ratio of >40% versus chronic obstructive pulmonary disease with a residual volume/total lung capacity ratio of >40%
