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

Group	VA Mean (SD)	Unadjusted	P	Adjusted	P
		OR (95% CI)		OR (95% CI)
TD (N = 1,252)	0.353 (0.074)	reference	0.03	reference	0.016
ASD (N = 1,330)	0.347 (0.073)	0.315 (0.111 to 0.897)		0.275 (0.096 to 0.789)

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).
