Demographics of the subjects used in the study: (A) sample from PING dataset comprising healthy individuals and (B) sample from ABIDE dataset comprising healthy individuals and individuals with ASD

A. PING dataset

Total number of subjects, N = 391

Males/females = 207/184

Age = 3.1–21.0 (12.1 ± 4.7) years

Ethnicity = European (86.70%), mixed (13.30%)

Handedness = Right-handed (86.71%), left-handed (9.97%), mixed (3.32%)

B. ABIDE dataset

Total number of subjects, N = 560

Males/females = 560/0

ASD/CTL = 266/294

Age = ASD: 7.1–35.0 (17.2 ± 6.4) years

CTL: 6.5–35.0 (17.0 ± 6.4) years

ASD (with ADOS), N = 218

ADOS Soc = 0–14 (6.9 ± 3.6)

ADOS Comm = 0–8 (3.3 ± 1.8)

ADOS severity = 1–9 (5.4 ± 2.3)

Note that ASD refers to total number of subjects categorized as autistic, while ASD with ADOS refers to a subset of the ASD subjects with concurrent measures of ADOS Soc and ADOS Comm. Means, with standard deviation, are given in parentheses.

CTL = healthy controls; ADOS Soc = Autism diagnostic observation schedule Social; ADOS Comm = ADOS Communication.
