Table 2.

Summary Data for Secondary Outcome Measures of 12-Month Peak Expiratory Flow and 12-Month Change in Clinical COPD Questionnaire for Patients Undergoing Endoscopic Dilation. Baseline Data Were Not Available for Peak Expiratory Flow, So These Values Represent the Measurement at 12 Months Rather Than a Change Over 12 Months.

Medication	Endoscopic Resection With Medical Treatment				Results
	Yes		No
	N	Median (IQR)	N	Median (IQR)
12-mo peak expiratory flow (L/min)
TMP-SMX	87	81 (66–90)	28	75 (68–89)	P = .92
12-mo change in clinical COPD questionnaire
TMP-SMX	87	−0.30 (−1.00, 0.10)	28	0.20 (−1.05, 0.47)	P = .45

IQR = interquartile range; TMP-SMX = trimethoprim-sulfamethoxazole.
