Values are presented as correlation coefficients
VFSS: videofluoroscopic swallowing study, PAS: penetration- aspiration scale, FDS: functional dysphagia scale, MEP: maximal expiratory pressure, MIP: maximal inspiratory pressure, PCF: peak cough flow, FVC: forced vital capacity, FEV1: forced ex-piratory volume in 1 s, K-MBI: Korean version of the modified Barthel index
