Representation of genetic association of the SNP rs13181 in the gene ERCC2 with the risk of breast cancer in terms of odds ratios of mutant genotypes.

Genotype	OR	95% CI (OR)	P Value
WM (AC)	2.086	1.246 to 3.492	0.0056
MM (CC)	4.412	2.413 to 8.068	P < 0.0001
WM + MM (AC+CC)	2.672	1.647 to 4.334	P < 0.0001

[CI-Confidence Interval; OR-Odds Ratio; WW-homozygous wild type; WM-heterozygous; MM-homozygous mutant; WM + MM-combined mutant genotype

WW was considered as the referent category during the calculation of ORs.

An OR >1 denotes positive association, while OR <1 signifies protective/negative association with cancer risk.]
