^a Ethnicity was asked separate from race, so total does not add to 100%.

^b Autism traits were classified by using the Social Responsiveness Scale (1st or 2nd edition).^34,35

^c Cognitive estimate was derived by using the Wechlser Abbreviated Scale of Intelligence (2nd edition)³⁶; the total N = 35 for cognitive estimate, as we did not collect it in all of the studies from which we drew data.

SD, standard deviation.
