  • This table shows the median (range) number of BA pairs from G1 and higher per CT scan at baseline and follow-up for two longitudinal datasets classified as bronchial widening and bronchial wall thickness according to cut-off values. No.: number; no. of BA pairs with Bout/A>1.1: the number of BA pairs with the ratio of bronchial outer diameter and adjacent artery diameter greater than 1.1; No. of BA pairs with Bout/A>1.5: the number of BA pairs with Bout/A ratio greater than 1.5; no. of BA pairs with Bin/A>0.8: the number of BA pairs with the ratio of bronchial lumen diameter and adjacent artery diameter greater than 0.8; no. of BA pairs with Bin/A>1.5: the number of BA pairs with the Bin/A ratio greater than 1.5; no. of BA pairs with Bwt/A>0.14: the number of BA pairs with the ratio of bronchial wall thickness and adjacent artery diameter greater than 0.14.

  • BA, bronchus artery.
