Scoring of online cases: The ‘possible UIP’ and ‘inconsistent with UIP’ categories were combined to generate a binary ‘typical UIP or possible UIP/inconsistent with UIP’ score
| Binary diagnosis score (Typical UIP or Possible UIP/inconsistent with UIP) | Interobserver agreement* |
|---|---|
| Disease subgroups | |
| MDT diagnosis—CHP (n=44) | 0.39 |
| MDT diagnosis—CTD-ILD (n=51) | 0.35 |
| MDT diagnosis—Idiopathic FLD (n=55) | 0.38 |
| Age subgroups | |
| Patient age <50 years (n=25) | 0.31 |
| Patient age 50–60 years (n=40) | 0.39 |
| Patient age 60–70 years (n=48) | 0.42 |
| Patient age >70 years (n=37) | 0.40 |
*Interobserver agreement expressed as Cohen's κ coefficient for this binary categorisation stratified according to multidisciplinary diagnosis and patient age.
CHP, chronic hypersensitivity pneumonitis; CTD-ILD, connective tissue disease related interstitial lung disease; FLD, fibrotic lung disease; MDT, multidisciplinary team; UIP, usual interstitial pneumonia.
