Table 1. Results of hypernasality measures including mean and SD values for EFn mean, EFn SD and EFn trend parameters across PD, HD and HC groups as well as results of ANOVA including F, p, and η2 values.

Based upon post-hoc Bonferroni comparisons, an asterisk (∗) indicates statistically significant differences between HD and HC groups at the p < 0.001 level of significance.
