Data are presented as mean±sd or median (interquartile range), unless otherwise stated. BMI: body mass index; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; Rrs6: resistance of the respiratory system measured at 6 Hz; Xrs6: reactance of the respiratory system measured at 6 Hz; EFLi: expiratory flow limitation index. #: includes HealthyAsym subjects.
