Article Figures & Data
Figures
- Fig. 1.
Demographic distribution of the asthma, intermediate type, and COPD groups. A: Age. B: Sex. C: Body mass index. D: Frequency of atopy. All the differences were significant by one-way analysis of variance.
- Fig. 2.
Smoking data of the asthma, intermediate type, and COPD groups. A: Percentage of smokers. B: Duration of smoking. C: Cigarettes per day. All the differences were significant by one-way analysis of variance.
- Fig. 3.
Pulmonary functions of the asthma, intermediate type, and COPD groups. A: Percent of predicted FEV1. B: Percent of predicted FVC. C: FEV1/FVC. All the differences were significant by one-way analysis of variance.
- Fig. 4.
Bronchodilator response and airway hyper-responsiveness in the asthma, intermediate type, and COPD groups. A: Percent with positive bronchodilator response (15% increase in FEV1). B: Post-bronchodilator response (increase in FEV1). C: Post-bronchodilator FEV1/FVC. D: Positivity on the methacholine provocation test. E: PC20 (provocational concentration of methacholine that produced a 20% decrease in FEV1). All the differences were significant by one-way analysis of variance.
- Fig. 5.
Frequency of emergency department visits (A) and admission rates (B) in the asthma, intermediate type, and COPD groups. All the differences were significant by one-way analysis of variance.
