^$Social responsiveness scale (SRS) SRS score is a standard socio-psychological biomarker indicating social impairments. It was only measured for 44/45 ASD and 29/30 TD.

^#Social Communications Questionnaire (SCQ) evaluates social functioning and communication skills based on a questionnaire.

^@Clinical Evaluation of Language Fundamentals-edition 4 (CELF-4) score is a marker of language impairment in ASD. Therefore it is highly significant in TD vs. LI+ and less so in TD vs LI−.

^*The abnormality score is computed from the proposed classification technique using the LOO validation.
