ATS CT grading of bronchial stenosis: 0, nonstenosis; I, ≤25%; II, >25% and ≤50%; III, >50% and ≤75%; IV, >75% and ≤90%; and V, >90% and ≤100%. The index of shortness of breath: 0, normal; 1, shortness of breath during brisk walking; 2, shortness of breath during walking at normal speed; 3, stopping walking due to shortness of breath when walking at normal speed; and 4, shortness of breath after slight activity; Prognostic grading: I, bronchial stenosis remission ≥75% for 3 months; II, bronchial stenosis remission >50% and ≤75% for 3 months; III, bronchial stenosis remission >25% and ≤50% for 3 months; and IV, bronchial stenosis remission ≤25%, mucosal lesions are still present.
