Associations between LCI and spirometric parameters.
| Normal LCI (%) | Abnormal LCI (%) | p-Value * | |
|---|---|---|---|
| Normal FEV1 (%) | 9 (45) | 9 (45) | 0.18 |
| Abnormal FEV1 (%) | 2 (10) | 0 (0) | |
| Normal FVC (%) | 10 (50) | 9 (45) | 0.36 |
| Abnormal FVC (%) | 1 (5) | 0 (0) | |
| Normal FEF 25–75% (%) | 9 (45) | 8 (40) | 0.66 |
| Abnormal FEF 25–75% (%) | 2 (10) | 1 (5) |
* Associations between LCI and spirometric parameters. Abbreviations: LCI = lung clearance index; FEV1 = forced expiratory volume in one second; FVC = forced vital capacity; FEF 25–75% = forced expiratory flow at 25–75%.
