Time to First and Second Pseudomonas aeruginosa Recurrence After Completion of the Clinical Trial, by Eradication Status

Recurrence	Nonsustained Eradicator (n = 77)	Sustained Eradicator (n = 172)	Overall (N = 249)	Difference or HR (95% CI)
First Pa recurrence
Participants with at least 1 Pa recurrence, No. (%)	65 (84.4)	103 (59.9)	168 (67.5)	Difference, 24.5% (12.5%–34.4%)
Median time, y, to first recurrence (95% CI)	1.0 (.75–1.75)	3.5 (2.75–4.75)	2.75 (2.50–3.50)	HR, 0.42 (.30– .57)
Second Pa recurrence
Participants with at least 2 Pa recurrences, No. (%)a	50 (76.9)	57 (55.3)	107 (63.7)	Difference, 21.6% (6.8%–34.5%)
Median time, y, to second recurrence since first recurrence (95% CI)	0.75 (.5–1.5)	2.00 (1.25–3.5)	1.50 (1.0–2.0)	HR, 0.55 (.38–.81)

Abbreviations: CI, confidence interval; HR, hazard ratio; Pa, Pseudomonas aeruginosa.

^a Denominator is the number of subjects with at least 1 Pa recurrence.
