  1. Nonclinical Samplea describes reports from nonclinical samples. Nonclinical Sample – BAP excludedb describes a subset of the previous sample, where it was specified that individuals from the BAP had been excluded. Matched ASC Casesc describes reports from available matched autism spectrum cases. Statistics calculated for all available reported data (see also Table 1). Malesd and Femalese refer to available data reported by sex, while Overallf refers to samples from studies reporting undifferentiated or combined male and female score. AQ: Autism-Spectrum Quotient; ASC: Autism spectrum conditions; BAP: broader autism phenotype; CI: confidence interval; N: number; SD: standard deviation.
