Table 3. The usual interstitial pneumonia (UIP) score model.
Characteristic | Points |
---|---|
Age, in years | |
50–59 | 2 |
≥60 | 3 |
Male sex | 1 |
Possible UIP+total traction bronchiectasis score ≥ 4 | 6 |
Total score possible | 10 |
The extent of radiographic traction bronchiectasis was scored in each lobe (right upper, middle, and lower lobes and left upper, lingula, and lower lobes) as 0-absent, 1-mild, 2-moderate, or 3-severe, and then summed to provide a total traction bronchiectasis score (see online supplementary figure S1 and ref. 14).
