Data are presented as mean±sd. CLE: continuous laryngoscopy exercise; IB: ipratropium bromide; EILO: exercise-induced laryngeal obstruction. All FEV1 values are litres during first second of forced expiration. All FVC are total forced vital capacity. #: at the day of inclusion, only baseline spirometry was performed; an additional spirometry was performed 20 min after receiving IB before the CLE test.
