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).
