Sputum neutrophil and eosinophil percentages in swimmers and cold-air athletes according to airway responsiveness
| Swimmers | Cold-air athletes | |||
| With AHR | Without AHR | With AHR | Without AHR | |
| Subjects n | 22 | 10 | 9 | 23 |
| Neutrophils % | 37.5 (34.9–40.1) | 36.5 (31.2–41.7) | 42.7 (36.8–48.6) | 36.5 (33.1–39.2) |
| Eosinophils % | 1.8 (1.5–2.1)* | 0.3 (0.2–0.3) | 1.4 (0.8–2.0)* | 0.3 (0.2–0.3) |
Inflammatory cell data are expressed as mean (95% confidence interval). AHR: airway hyperresponsiveness. *: p<0.05 versus athletes (cold-air or swimmers) without AHR.
