Plain-language summary

This study aims to establish normative values for respiratory oscillometry in the Polish pediatric population. It is designed as a multicentre, population-based, prospective cohort study including children and adolescents aged 3-18 years. The results will provide reference standards for respiratory oscillometry that may support the diagnosis and monitoring of respiratory diseases in clinical practice and research.
