Table 3:

Fit indices for the unadjusted structural equation model for the mediated effect of postpartum maternal toenail As levels on gestational through DNMT3A DNAm, and the mediated effect of postpartum maternal toenail As levels on birth weight through gestational age and DNMT3A DNAm. As = arsenic; DNAm = DNA methylation.
