Allele and genotype frequencies of polymorphisms in DARC and CCBP2 in relation to lymph node metastasis.

LN+, positive lymph node; LN−, negative lymph node; OR, odds ratio; CI, confidence interval; UTR, untranslated region; N.S., not significant; N.A., not applicable.§some cases failed to be genotyped and these genotype data were thus missing.*unadjusted P-value of two-sided χ2 tests.**corrected for multiple testing by false discovery rate.#calculated by logistic regression, adjusted for age, tumor size, ER, PR, HER2, grade, and histology type.
