Table 3 An overview of three scoring systems for chest radiography in cystic fibrosis, adapted from the original publications. The modification of the Chrispin-Norman score from 1982 [19] also included enlarged hilar lymph nodes in the score, in this table included in the parenchyma score. In the Wisconsin scoring system [18] each scoring component is weighted, the range for each component score was calculated by using the formula given in the publication
