  • Results are shown as Spearman (or Pearson) correlation coefficient (r) and (95% CI). PRAGMA-CF: The Perth-Rotterdam Annotated Grid Morphometric Analysis for Cystic Fibrosis; BA: bronchial-artery; %BE_PRAGMA-CF: percentage of lung volume occupied by bronchiectasis on inspiratory chest CT scan assessed by PRAGMA-CF; %BE_Automatic-BA (Bout/A>1.1): percentage of BA pairs with Bout/A ratio greater than 1.1 quantified by the automatic BA analysis; %BE_Automatic-BA (Bout/A>1.5): percentage of BA pairs with Bout/A ratio greater than 1.5 quantified by the automatic BA analysis; %BE_Automatic-BA (Bin/A>0.8): percentage of BA pairs with Bin/A ratio greater than 0.8 quantified by the automatic BA analysis; %BE_Automatic-BA (Bin/A>1.5): percentage of BA pairs with Bin/A ratio greater than 1.5 quantified by the automatic BA analysis.
