Communication verbal scores were available for 153 ASD and 114 NA cases and nonverbal scores for 21 ASD and 2 NA cases. Due to the limited number of NA cases receiving the nonverbal algorithm, the diagnostic comparison was not performed for the K-ADI-R Comm-Nonverbal; all significant at p < 0.001, except for K-ADI-R Comm-Nonverbal.
ASD, autism spectrum disorder; Comm, communication; K-ADI-R, Korean Autism Diagnostic Interview-Revised; K-ADOS, Korean Autism Diagnostic Observation Schedule; NA, no-ASD; RRB, restricted and repetitive behaviors; SD, standard deviation.
