Figure 2From: Reproductive aging-associated common genetic variants and the risk of breast cancerThe associations between groups defined by quintiles of genetic risk scores (GRSs) and risk of breast cancer by estrogen receptor (ER) status in the Nurses' Health Study and the Women's Genome Health Study. (a) Count GRS for age at menarche. (b) Count GRS for age at natural menopause. (c) Count GRS for breast cancer-associated SNPs. CI, confidence interval.Back to article page
