General characteristics of patients with COPD and healthy controls.
| Patients with COPD (n = 7) | Healthy controls (n = 7) | p value | |
|---|---|---|---|
| Sex | Male | Male | |
| Age (year) | 64.71 ± 3.06 | 71.14 ± 4.77 | 0.28 |
| Smoke (pack-years) | 28.36 ± 5.70 | 0.00 | 0.00 |
| Height (cm) | 162.86 ± 1.10 | 167.29 ± 1.97 | 0.07 |
| Weight (kg) | 62.86 ± 3.84 | 70.43 ± 3.27 | 0.16 |
| BMI (kg/m2) | 23.66 ± 1.32 | 25.15 ± 1.05 | 0.39 |
| FEV1 (L) | 2.15 ± 0.33 | 3.31 ± 0.13 | 0.01 |
| FVC (L) | 3.42 ± 0.35 | 4.08 ± 0.12 | 0.12 |
| FEV1/ FVC (%) | 60.28 ± 4.43 | 82.52 ± 2.28 | 0.00 |
| FEV1%Pred (%) | 68.56 ± 8.99 | 97.26 ± 2.88 | 0.02 |
Variables are expressed as mean ± standard error of the mean (SEM). Italicized p values resulted from Student t test for parametric variables between the two groups are statistically significant, ie., p < 0.05.
BMI, body mass index; FVC, forced vital capacity; FEV1, forced expiratory volume in 1 s; %Pred, percent predicted.
