Data are presented as mean±sd unless otherwise stated. MIP: maximal inspiratory pressure; F: female; M: male; ns: nonsignificant; BMI: body mass index; FVC: forced vital capacity; % pred: percentage of predicted value; FEV1: forced expiratory volume in 1 s; MEP: maximal expiratory pressure; SNIP: sniff nasal inspiratory pressure. #: there is no predictive equation defined for SNIP in female children, so data are only shown for males.
