Data logarithmically transformed, ANCOVA analysis. ‘Completed’ patients are defined as patients who completed the study; that is, those who have a baseline and week 24 result.
*Adjusted difference (CDPI – TIS) obtained using formula (M× (ratio−1)), where M is the unadjusted TIS geometric mean.
†Adjusted difference (CDPI – TIS) obtained using formula (M ×( ratio−1)), where M is the TIS geometric mean adjusted for baseline FEV_{1}% predicted and pooled centre.
ANCOVA, analysis of covariance; CDPI, Colobreathe dry powder for inhalation; FEV_{1}, forced expiratory volume in 1 s; LOCF, last observation carried forward; TIS, tobramycin inhaler solution.
