In Italics: >66% ASD and <33% MAD. Odds ratios >1.00 indicate increasing likelihood of ASD, whereas values <1.00 indicate increasing likelihood of being assigned to MAD. ADOS: Autism Diagnostic Observation Schedule; Com: communication domain; Social: social interaction domain; RRB: restricted repetitive behaviors; ASD: autism spectrum disorder; MAD: mood and anxiety disorder.
