- Bolded p-values indicate significant differences between PTH and HC; diff = differences between the means of speech measure between PTH patients during headache and HC, for assessing the direction of differences only. Negative numbers indicate lower values, and positive numbers indicate higher values for patients with PTH during headache
- Normalized = the value is normalized by a large corpus (for details refer to Table 1)
- Speech features that are significantly different between groups are color-coded for easy cross-referencing with Speech Features shown in Table 1
