*
= Scores of <93.8 considered to present with aphasia.
^
= Data from the Apraxia of Speech Rating Scale (Strand et al., 2014), subsection 1 was collected. A higher score on subsection 1 of the ASRS indicated presence of more severe apraxia of speech and the maximum score was 4. Not all participants had this measure: N=60 in CS group, N=16 in PNT group, 34 in CS+PNT group.
^^
= Reported for only connected speech task.
^^^
= Reported for only naming task. There are 175 possible responses on PNT; this number considers the number of no responses.
