- * = statistical difference when compared vs. children with ASD of normal neurodevelopmental level (p < 0.001); # = statistical difference when compared vs. children with ASD and a mild developmental delay (p < 0.001)
- The distributions of the ABC, CARS, SRS, and CWB scores in the three groups were skewed, so the Kruskal-Wallis test was used
- ABC Autism Behavior Checklist; SRS Social Responsiveness Scale; CARS Childhood Autism Rating Scale; CWB Communication warning behavior; ASD autism spectrum disorder; DD developmental delay
