| Comparison by survival status | |||
|---|---|---|---|
| All CF patients (n=584) | Died (n=137) | Alive (n=447) | |
| Age (years) | 21 (7) | 22 (7) | 21 (7) |
| Sex (M/F) | 323/261 | 73/64 | 250/197 |
| FEV1 (l) | 1.8 (1.0) | 1.1 (0.5) | 2.1 (1.0)1-151 |
| % predicted FEV1 | 52 (26) | 32 (15) | 58 (25)1-151 |
| % ideal weight | 92 (18) | 82 (15) | 95 (18) 1-151 |

Data are presented as mean (SD) or numbers of patients.
FEV1 = forced expiratory volume in one second; % ideal weight = weight as percentage of the predicted ideal weight; Pao 2= arterial oxygen tension; Paco 2 = arterial carbon dioxide tension.
↵1-150 p<0.01,
↵1-151 p<0.0001 for unpaired t test of mean of corresponding groups.
