	CD mean (SD)	CS mean (SD)	HC mean (SD)	Comparison
Silent pauses per 100 words	18.8 (7.7)	14.8 (3.0)	12.5 (3.5)	p = 0.01**
Fillers per 100 words	2.6 (1.6)	3.9 (2.3)	3.1 (2.0)	p = 0.203
False starts per 100 words	0.54 (1.6)	0.70 (0.70)	1.0 (1.1)	p = 0.220
Self-interrupted sentences per total sentences	0.18 (0.12)	0.17 (0.10)	0.14 (0.10)	p = 0.294
Disfluencies per 100 words	23.1 (8.3)	20.5 (3.9)	17.7 (5.1)	p = 0.017*
Mean pause length (>120 ms)	0.78 (0.21)	0.74 (0.18)	0.71 (0.30)	p = 0.138
Maximum pause length (>120 ms)	3.5 (1.7)	3.0 (1.5)	2.4 (1.3)	p = 0.007**
Mean filler length	0.45 (0.16)	0.50 (0.15)	0.43 (0.1)	p = 0.151

Note:

^*sig. at p-level 0.05,

^**sig. at p-level 0.01, ***sig. at p-level 0.001. Bold type numbers are significant at the Bonferroni corrected alpha level p ≤ 0.006.
