Frequencies and mean <i>CCR5</i> expression by <i>CCR5</i> SNP/haplotype category.

†Linear regression for the association between CCR5 expression and CCR5 SNP/haplotype: Continuous outcome of placental expression. β: Beta coefficient, 95% CI: 95% Confidence Interval for the Beta, p: p-value. ‡Logistic regression for the association between CCR5 expression and CCR5 SNP/haplotype: Dichotomous outcome of high vs. low placental expression of CCR5 dichotomized at the median value. OR: Odds Ratio, 95% CI: 95% Confidence Interval for the Odds Ratio. £ # Copies: Number of copies of haplotype: 0, 1, or 2 copies possible per subject. SNPs and haplotypes categorized as having one or more copies of the variant allele or haplotype compared to zero copies.
