Table 5:

Results from the trinomial WQS regression, with positively constrained betas, for the two logit models with urinary biomarker concentrations quantiled (into quartiles) in generalized logit models (ordered by outcome category with TD as the reference level) adjusted for covariates^a (N=207).

	ASD vs TD	non-TD vs TD
OR^b (95% CI)	1.47 (1.45, 1.49)	1.58 (1.56, 1.60)
P value	0.098^ǂ	0.032^*
Urinary biomarker^a	Weights (%)	Weights (%)
BPA	10.8	17.5
ETPB	55.4	16.8
MEPB	3.8	52.1
PRPB	30.0	13.5

Adjusted for pre-pregnancy body mass index, prenatal vitamin use (yes/no), homeowner status (yes/no), birth year, and child’s sex.

The OR represents the odds of having ASD or non-TD compared to TD for a one unit increase (on a scale from 0 to 3) in the WQS index score.

P-value between 0.05 – 0.12 is borderline statistically significant.

P-value <0.05 is statistically significant.
