Multivariable associations between cord blood metal concentrations and birth outcomes after controlling for SES and maternal education in the final multivariable linear regression models for birth outcomes.

Birth Outcome Variables	N	Lead ^a		Mercury ^a		Aluminum ^a		Manganese ^b
Birth Outcome Variables	N	Adjusted Slope Coefficient	p	Adjusted Slope Coefficient	p	Adjusted Slope Coefficient	p	Adjusted Slope Coefficient	p
Birth weight (kg)	96	0.01	0.91	0.16	0.18	0.01	0.87	0.002	0.53
Crown-heel length (cm)	48	0.48	0.68	−1.31	0.47	−0.15	0.87	−0.013	0.79
Head circumference (cm)	55	−2.30	<0.01	−0.90	0.34	−0.28	0.59	−0.034	0.19
1-minute Apgar score	77	−0.15	0.56	−0.011 ^c	0.98	−0.14	0.50	<0.001 ^d	0.92
Gestational age (weeks)	73	0.30	0.77	−0.24	0.87	−1.46	0.10	−0.006	0.87

^a For lead, mercury, and aluminum ln-transformed cord blood metal concentrations were used; ^b For ease of understanding, the adjusted slope coefficients for manganese are provided with three decimal places; ^c For ease of understanding, the adjusted slope coefficient for 1-min Apgar score in relation to mercury is provided with three decimal places; ^d The actual value was 0.00097.
