Inhaled tobramycin (TNS) vs placebo

Eradication of P aeruginosa from the respiratory tract: proportion with positive respiratory culture for P aeruginosa · adults and children with cystic fibrosis and a positive microbiological isolate of P aeruginosa from a respiratory tract specimen

Inhaled tobramycin (TNS) may leads to lower eradication of P aeruginosa from the respiratory tract: proportion… compared with placebo (low certainty).

Inhaled tobramycin (TNS) (28 days) vs TNS (56 days)

Frequency of infective pulmonary exacerbations: number of exacerbations per patient year · adults and children with cystic fibrosis and a positive microbiological isolate of P aeruginosa from a respiratory tract specimen

It is very uncertain whether inhaled tobramycin (TNS) (28 days) changes frequency of infective pulmonary exacerbations: number of… compared with TNS (56 days) (very low certainty).

Cycled inhaled tobramycin vs culture‐based TNS

Pulmonary exacerbations · adults and children with cystic fibrosis and a positive microbiological isolate of P aeruginosa from a respiratory tract specimen

Cycled inhaled tobramycin (TNS) probably leads to lower frequency of infective pulmonary exacerbations: proportion of… compared with culture‐based TNS (moderate certainty).
