a.

Percentages are row totals relative to all treatment events studied

b.

Treatment events could include more than one route of antimicrobial administration

c.

Treatment events consisting entirely of antimicrobials considered inactive against P. aeruginosa

SD = standard deviation, IQR = interquartile range, ppFEV1=percent predicted forced expiratory volume in 1 sec. Percentages are column totals unless otherwise noted
