Reply to Korppi and Riikonen

“…We highly appreciate Korppi and Riikonen's comment to our article regarding trajectories of lung function and bronchial hyper-reactivity (BHR) during puberty in children with bronchiolitis in infancy. 1,2 The comment offers an overview of the published literature based on three Finnish and Norwegian cohorts following children hospitalized for bronchiolitis in early age. Our published study is actually a substudy of a larger study of approximately 200 young adults with previous bronchiolitis and matched controls, performed at 17-20 years of age.…”

However, testing of reversibility cannot reliably be performed at the same day as tests for BHR.…”
