Implication

Observational analysis revealed that allergic sensitisation affects FeNO levels in adolescents, suggesting sensitisation-specific cutoffs may improve asthma diagnosis.

Key Points

A higher level of fractional exhaled nitric oxide is linked to allergic sensitisation in adolescents, affecting asthma risk.
The 95th percentile for FeNO values among sensitised adolescents was significantly higher than the recommended fixed cutoffs.
Allergic sensitisation type influences FeNO levels, necessitating adjusted cutoffs for accurate asthma diagnosis.
Exhaled nitric oxide levels above specific percentiles relate to respiratory symptoms like wheeze and asthma in sensitised individuals.
