Table 4.

Videofluoroscopic swallow study (VFSS) vs. fiberoptic endoscopic evaluation of swallowing (FEES) for all swallows (linked and unlinked).

	Positive	Total	%
VFSS aspiration	18	216	8.3%
FEES aspiration	4	107	3.7%
VFSS penetration	51	216	23.6%
FEES penetration	59	107	55.1%

This table shows the results of all swallows on VFSS and FEES. FEES identified penetration significantly more than VFSS (p < 0.001), while there was no significant difference between VFSS and FEES for aspiration (p = 0.123).
