  • 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).
