  Respiratory bronchiolitis with ILD (RBILD) | 14 | 10 | 6 |
  Desquamative interstitial pneumonia (DIP) | 3 | 3 | 3 |
  Cryptogenic organizing pneumonia (COP) | 13 | 12 | 10 |
  Acute interstitial pneumonia (AIP) | 1 | 1 | 0 |
  Lymphocytic interstitial pneumonia (LIP) | 3 | 3 | 3 |
Non idiopathic interstitial pneumonia | 3 | 11 | 25 |
  Hypersensitivity pneumonitis (HP) | 0 | 3 | 10 |
  Langerhans cell histiocytosis (LCH) | 3 | 7 | 7 |
