| Diagnosis of the different IP subtypes in 3 steps | |||
| Interstitial lung diseases (n = 88) | Step 1: histology alone (pattern) | Step 2: histology + clinical information | Step 3: interdisciplinary case evaluation |
| Idiopathic interstitial pneumonia or pattern* | 85 | 77 | 63 |
| IPF/Usual interstitial pneumonia (UIP) | 31 | 29 | 27 |
| Non specific interstitial pneumonia (NSIP) | 21 | 20 | 14 |

| Desquamative interstitial pneumonia (DIP) | 3 | 3 | 3 |
| Cryptogenic organizing pneumonia (COP) | 13 | 12 | 10 |
| Acute interstitial pneumonia (AIP) | 1 | 1 | 0 |
