Haplotype analysis of the association between IGF1R under three genetic models and the risk of breast cancer.

Percentage of genotype among group.OR (CI95%)1: Univariate logistic regression model.OR (CI95%)2: Multivariate logistic regression model. Adjusted for age at diagnosis, BMI, age at menarche, and age at first parturition.a Breast cancer risk for heterozygotes (AB) and homozygotes (BB), each compared with major allele homozygotes (AA) in model adjusted genotyping.b Breast cancer risk for minor allele carriers (AB/BB) compared with major allele homozygotes (AA) in model adjusted for genotyping.c Breast cancer risk for minor allele homozygotes (BB) compared with major allele carriers (AA/AB) in model adjusted for genotyping.SNPs’ location on chromosome number.
