2. Figure 1
Meta-analysis of the association of birth weight (corrected for sex and gestation) with fetal rs genotype across six studies, arranged in order of increasing size. The effect size (in grams) and 95% CI per risk allele is presented. Combined per-allele difference=18 g (95% CI 7–29 g); P=.001; I2=21.0%.

3. Figure 2
Meta-analysis of the association of birth weight (corrected for sex and gestation) with maternal rs genotype across three studies, arranged in order of increasing size. The effect size (in grams) and 95% CI per risk allele is presented. Combined per-allele difference=30 g (95% CI 15–45 g); P=2.8×10−5. I2=14.3%.
