*Table shows values of regression coefficients for actigraphy term in the model equation provided in the data analysis section. ABC, Aberrant Behavior Checklist; ABI, Autism Behavior Inventory; ASD, autism spectrum disorder; CV, coefficient of variation; SD, standard deviation; SRS-2, Social Responsiveness Scale 2. *p < 0.05; **p < 0.01; ***p < 0.001 (with FDR adjustment).
