Table 1 Clinical data of 183 patients with CF according to their P aeruginosa status.
| Free (n = 68) | Intermittent (n = 27) | Chronic† (n = 88) | |
|---|---|---|---|
| Classified according to sputum (n) | 11 | 5 | 60 |
| Classified according to swab (n) | 57 | 22 | 28 |
| Age (years)* | 11.4 (2–29) | 14.5 (2–41) | 21.5 (3–38) |
| Weight for height (%)* | 103 (62–130) | 107 (88–148) | 105 (78–158) |
| FEV1 (% predicted)* | 97 (62–147) | 94 (48–143) | 75 (21–128) |
| IgG (mg/dl)* | 842 (294–1962) | 966 (296–2440) | 1293 (654–2575) |
| C‐reactive protein (mg/dl)* | 0.18 (0.00–1.36) | 0.14 (0.01–0.58) | 0.64 (0.00–3.90) |
| Detection of mucoid strains (n/N) | 0/68 | 15/27 | 84/88 |
*Data expressed as mean (range).
†Duration of infection for median of 11.5 years (range 1.5–26).
There were significant differences between the groups in FEV1 depending on age (p = 0.025) but not group membership (p = 0.35, two way ANOVA).
