Correlation between VFSS results and MEP, MIP, PCF, FVC, FEV1, and K-MBI

	PAS	FDS
MEP	−0.528**	−0.561**
MIP	−0.558**	−0.477**
PCF	−0.511**	−0.472**
FVC	−0.142	−0.115
FEV1	−0.185	−0.178
K-MBI	−0.436**	−0.250*

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

*P<0.05, **P<0.01 by partial correlation analysis after adjust-ment for age
