Associations between risk of breast cancer and haplotypes of two HDC variants (rs7164386 and rs7182203) and two HRH3 variants (rs3787429 and rs3787430).

OR odd ratio, CI confidence interval.Bonferroni’s multiple adjustment was applied to the level of significance, which was set at PaSNPs of haplotype are (in sequence) rs7164386 and rs7182203 for HDC, and rs3787429 and rs3787430 for HRH3, respectively.bP values were calculated from two-sided chi-square tests or Fisher’s exact tests.cP values were calculated by unconditional logistic regression adjusted for age, menopausal state and body mass index.
