^aSemi-parametric regression adjusted for country, ADOS CSS and age for males and robust regression adjusted for ADOS CSS for females

^bRobust regression adjusted for country and corrected FSIQ for males and only corrected FSIQ for females; β = estimated regression coefficient; se = standard error. *p value remained < 0.05 after adjustment for multiple testing

Italic values indicate significance prior to adjustment for multiple testing
