Table 2.

Mean difference in pre– to post–PEx treatment ppFEV1, return to ≥90% of baseline ppFEV1, and time to next PEx requiring i.v. antibiotics (IPTW unadjusted and adjusted) in inhaled antibiotic-exposed patients

  IPTW Unadjusted
 IPTW Adjusted
Results P Value Results P Value
Change in ppFEV1, estimate (95% CI) −0.66% (−1.38 to 0.07) 0.077 −1.11% (−1.83 to −0.38) 0.003
Return to ≥90% of baseline ppFEV1, odds ratio (95% CI) 1.09 (0.96 to 1.24) 0.16 0.94 (0.82 to 1.07) 0.34
Time to next PEx hazard ratio (95% CI) 1.01 (0.95 to 1.07) 0.72 1.05 (0.99 to 1.12) 0.098

Definition of abbreviations: CI = confidence interval; IPTW = inverse probability of treatment weighting; i.v. = intravenous; PEx = pulmonary exacerbation; ppFEV1 = percent predicted forced expiratory volume in 1 second.
