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
