Radiological diagnoses within the cohort of patients with physician-diagnosed IPF
| Radiological diagnosis | Number of cases (%) | Number of men (%) | Mean age at diagnosis (years) | Mean FVC % predicted | Mean Tlco % predicted |
|---|---|---|---|---|---|
| Definite usual interstitial pneumonia | 110 (36) | 86 (78) | 74.2 (8.3) | 83.9 (17.9) | 43.4 (14.5) |
| Probable usual interstitial pneumonia | 101 (33) | 72 (71) | 72.1 (8.6) | 86.7 (17.2) | 46.8 (15.2) |
| Fibrotic non-specific interstitial pneumonitis | 28 (9) | 14 (50) | 71.3 (7.4) | 83.6 (19.3) | 45.4 (13.9) |
| Unable to classify | 67 (22) | 44 (66) | 71.6 (8.8) | 82.0 (25.5) | 46.9 (21.7) |
FVC, forced vital capacity; IPF, idiopathic pulmonary fibrosis; Tlco, carbon monoxide transfer factor.
