Figure 5a. (a) Bar graph shows correlation of number of patients with maximal lesion extent score lower than 7 versus lesion distribution categories. Twenty-seven patients who survived and had an extent score lower than 7 belonged to categories I-III, with involvement of three or fewer lung zones. (b) Bar graph shows correlation of number of patients with maximal lesion extent score of 7 or higher versus lesion distribution categories. The patients with a lesion extent score of 7 or higher (25 patients) had a high mortality rate (20 of the 25 died), especially those patients with lesion distributions in categories IV-VI. Note that all three patients with category III lesion distributions who died had thoracic malignancies.
