Subjects’ Demographic And Functional Characteristics
| FE | ACO | Emphysema Hyperinflation | P-Value | |
|---|---|---|---|---|
| Age (years, mean ± SD) | 67.0 ±7.8 | 60.7 ± 7.8 | 67.0 ± 7.8 | 0.06 |
| Male gender (n/total) | 15/21 | 7/14 | 13/26 | 0.99 |
| Smoking load | 46.7 ± 24.5 | 60.2 ± 27.6 | 48.5±30.2 | 0.33 |
| FEV1% (mean ± SD) | 58.4 ± 20.7 | 68.3 ± 15.3* | 52.3 ± 16.3* | 0.03 |
| FVC% (mean ± SD) | 92.0 ± 25.1 | 100.0 ± 19.0 | 91.3 ± 18.5 | 0.41 |
Notes: Used ANOVA for categorical numbers and chi-square for gender. *Multiple comparison showed difference between ACO and emphysema/hyperinflation groups (p=0.02). Bold text indicates statistical significance.
Abbreviations: ACO, asthma/COPD overlap; FE, frequent exacerbator; FEV1%, forced expiratory volume in the first second % predicted; FVC%, forced vital capacity % predicted.
