(B) DLD group was composed of 7 (11.1%) toddlers with ED, 18 (28.6%) with ND, and 38 (60.3%) with RD. (C) In total, there were 51 (30.7%) ED, 46 (24.7%) ND, and 69 (41.6%) RD. Significant group difference in proportion was observed between ASD and DLD group using chi square test (χ²=21.327, p<0.001). ASD, autism spectrum disorder; DLD, developmental language delay; ED, expressive language dominant type; ND, non-dominant type; RD, receptive language dominant.
