Strengths
It is one of the few studies that evaluated IPFT in children with airway
anomalies with a reasonable number of participants. It is possibly the
first study in which follow-up IPFT was done in airway anomalies
patients. IPFT parameters were compared with a similar number of
controls, matched with birth weight, sex and age. The IPFT was performed
successfully in most children with mild sedation, spontaneous sleep or
when the child is quietly watching videos on a mobile. Reporting of IPFT
patterns and bronchoscopy findings was done by three persons
independently.
