Genotype distributions and allele frequencies of seven polymorphisms under study between patients and controls and their risk prediction for breast cancer under three genetic models of inheritance.

Abbreviations: W/M, wild allele/mutant allele; OR, odds ratio; 95% CI, 95% confidence interval. P for χ2 test was calculated based on the 3×2 contingency tables for genotype comparisons and on the 2×2 contingency tables for allele comparisons. *Controlling for age at enrollment.
