Differences in Swallowing between High and Low Concentration Taste Stimuli

Table 5

Descriptive statistics for strength-normalized measures of anterior tongue-palate swallowing pressures (in % of effortful saliva swallow amplitudes), shown by taste quality, stimulus concentration, participant age group, and genetic taste status.
