Note: F-tests obtained from two-way analysis of variance.
Scores obtained using exact testing in logistic regression.
BCST = basic communication skills training.
AAC = augmentative and alternative communication.
SLP = speech language pathology.
+
NA = not available; no variability in the BCST group.
