Table 4. . Association between two cis-single nucleotide polymorphisms at the HIF3A locus (rs8102595, rs3826795) and birth weight.

Single nucleotide polymorphism	Est.	95% CI	p-value
rs8102595	0.39	(-0.89, 1.7)	0.55
rs3826795	0.059	(-1.0, 1.2)	0.92

Regression coefficients (Est.) and 95% CI are reported as percentage change in birth weight per copy of the effect allele. p-values are two-sided. Analysis was done by linear regression of log-transformed birth weight against each SNP (additive genetic model), adjusting for ethnicity and child sex. The effect allele of rs8102595 is G and the effect allele of rs3826795 is C.
