Values are the mean ± standard deviation for age, time parameters, and residue; otherwise, values are the number of patients

OTT oral transit time, PDT pharyngeal delayed time, PTT pharyngeal transit time

p values were obtained from Fisher’s exact test, Independent t test, *Mann–Whitney U test, **Paired t test, and ***McNemar test
