Goblet Cell Hyperplasia Score: Change by Baseline Score

Baseline Goblet Cell Hyperplasia Score* (N = 54 Airway Biopsies)	Improved	No Change	Worsened
0	0	5	2
1	6	13	3
2	14	2	1
3	7	1	0

Table presents changes from baseline to 90 days and 120 days after the procedure for the left and right lungs, respectively. One biopsy sample is assessed for each lung at each of the two time points (baseline and follow-up).

^*Graded on a 4-point scale in which 0 = normal ratio of goblet cells to ciliated bronchial epithelial cells (1 goblet cell per 10 or more bronchial epithelial cells); 1 = mild goblet cell hyperplasia (1 goblet cell per approximately 3–10 ciliated bronchial epithelial cells); 2 = moderate goblet cell hyperplasia (approaching 1 goblet cell per ciliated bronchial epithelial cell); and 3 = severe goblet cell hyperplasia (>1 goblet cell per ciliated bronchial epithelial cell).
