Study population demographics—first section: the number of participants (N), as well as number of female participants (Female N), included in the study after all quality assessment procedures for the TD and ASD cohorts. Study population demographics—second section: mean (and SD) age (first row), GAI score (second row), and SRS score (third row) for the TD and ASD cohorts. Study population age distribution—first section: minimum (first row) and maximum (second row) age for the TD and ASD cohorts. Study population age distribution—second section: number of subjects, ages between 4 and 8 years (first row), between 8 and 12 years (second row), and between 12 and 16 years (third row), for TD and ASD cohorts.
