Multiple linear regression analysis of risk factors according to dysphagia severity as assessed using FDS

Independent variable β P-value 95% CI R2 VIF
MEP −0.423 <0.001*** −0.532-−0.193 0.336 5.676
PCF −0.218 0.031* −0.102-−0.005 1.677

FDS: functional dysphagia scale, MEP: maximal expiratory pressure, PCF: peak cough flow, β: regression coefficient, CI: confidence interval, VIF: variance inflation factor
