Predictor	Full Dataset	College Graduates Only
Predictor	Multiplicative Increase (95% CI)	Multiplicative Increase (95% CI)
Number of Electronics in the Home
Stereo & Video Electronics other than Televisions	1.14/item (0.97 – 1.35)	1.13/item (0.95 – 1.35)
Regularly eats organic
No	Reference	Reference
Yes	0.61 (0.37 – 1.01)	0.62 (0.37 – 1.06)

R²	0.22 (p=0.006)^*	0.18 (p=0.03)^*

Statistically significant at the α = 0.05 level.

Coefficients represent the multiplicative increase in breast milk concentrations per item (for continuous variables) or relative to the reference group (for categorical variables).
