Mean (95% CI) survival of patients with idiopathic UIP and of those with UIP and connective tissue disease
| Variable | Idiopathic UIP(n = 64) | UIP + CTD(n = 12) | Total(n = 76) |
|---|---|---|---|
| CTD, connective tissue disease; FF, fibroblast focus. | |||
| *Mean survival was used since over half of the patients (4/6) were alive by the end of the study. | |||
