Note. SMI-LCI = children with speech motor impairment and language comprehension impairment; ANAR = children who have anarthria and are unable to speak; SMI-LCT = children with speech motor impairment and typical language comprehension. Degrees of freedom: ANAR as the reference group: 2, 37; SMI-LCI as the reference group: 1, 23.
Significance codes: *0.01; **0.001; ***0.
