Comparison of the levels of serum VA between children with ASD and TD in different gender.

Group	VA mean(SD)	Unadjusted	P	Adjusted	P
		OR (95% CI)		OR (95% CI)
Boys
TD (N = 822)	0.353 (0.076)	reference	0.011	reference	0.007
ASD (N = 1,087)	0.344 (0.075)	0.207 (0.062 to 0.693)		0.190 (0.056 to 0.639)
Girls
TD (N = 430)	0.354 (0.071)	reference	0.294	reference	0.441
ASD (N = 244)	0.360 (0.069)	3.343 (0.351 to 31.794)		2.443 (0.252 to 23.665)
Gender
Boys with ASD (N = 1,087)	0.344 (0.075)	reference	0.003	reference	0.004
Girls with ASD (N = 244)	0.360 (0.069)	17.214 (2.591 to 114.375)		16.559 (2.471 to 110.959)

TD, typically developing; ASD, autism spectrum disorder. OR, odds ratio; CI, confidence interval.

Uni-variate Logistics Regression was used for unadjusted model and Binary Logistics Regression was used for adjusted model (adjusted for age).
