BSS distribution across each genotype of 3 promoter SNPs, stratified by race. The scatter plots of the distribution of BSS across genotypes of 3 promoter SNPs (rs1432623, rs11168068, and rs2400707) separately for Caucasian and African American infants. We further overlay box-and-whisker plot of BSS on each scatter plot. P values were obtained from non-parametric Kruskal-Wallis test
