Figure 2: Percentage bar graph of the location of the leading edge of the barium at swallow onset for each food type in stroke and control subjects. For liquid and two-phase food, the leading edge was lower in the foodway at swallow onset in the stroke group than with in controls (P = 0.057 for liquid and P = 0.03 for two-phase). For corned beef hash, the leading edge was usually in the oropharynx in both groups (P = 0.80). The number of recordings is shown in parentheses for each food type. OC, oral cavity; UOP, upper oropharynx; VAL, valleculae; HYP, hypopharynx; FPS, floor of piriform sinus
