Velopharyngeal junction closure (seconds)	Controls	−0.005 (0.03)	0.059 (0.002, 0.117)
Laryngeal vestibule closure (seconds)	Patients	0.16 (0.06)	0.152 (0.024, 0.277)

Upper esophageal sphincter closure (seconds)	Controls	0.80 (0.04)	0.07 (0.001, 0.127)
Piecemeal deglutition (5-point scale, 0–4)	Patients	1.248 (0.17)	0.557 (0.235, 0.878)
Piecemeal deglutition (5-point scale, 0–4)	Controls	0.691 (0.17)	0.557 (0.235, 0.878)

Significant VFS parameters and their estimated means plus standard errors for patients and controls separately, in combination with the 95% CI of the mean difference between both groups. In the random intercept model, the data have been adjusted for electrode position and electrical current status (current on/off) which are both not significant
