  1. Three autistic girls and 1 autistic boy had missing SRS T-scores; SCQ scores were missing for 1 TD boy. CSS ADOS-2 calibrated severity score, SA social affect, RRB repetitive behaviors/restricted interests. Chi-squared tests with Yates’ continuity correction tested for diagnostic group differences in sex ratio and maternal educational attainment. P values and Cohen’s d values for main effects of sex and diagnosis are shown (simple linear model with the whole sample; there were no significant interactions), as well as p and Cohen’s d values of sex differences in the ASD group only
