Associations between limb abnormalities and mixture exposure of Pb, Cd, Hg, Se, Mn.

	adjusted OR	95%CI		p-value	Sum of positive coefficient	Sum of negative coefficient
All congenital limb abnormalities	0.85	0.72	1.02	0.073	0	−0.16
All polydactylies	0.92	0.72	1.17	0.497	0.03	−0.12
All syndactylies	0.83	0.63	1.11	0.207	0.02	−0.20

The adjusted odds ratio are interpreted as the effect on limb abnormalities of increasing every one quantile unit of mixture exposure of Pb, Cd, Hg, Se, and Mn in quantile g-computation.

Adjusted for maternal age (categorical), maternal smoking (categorical), maternal alcohol intake (categorical), paternal smoking (categorical), infant sex.
