Figure 2From: Quantitative measures of estrogen receptor expression in relation to breast cancer-specific mortality risk among white women and black womenPercentage of tumor cell nuclei positively stained for estrogen receptor and breast cancer-specific mortality risk. Adjusted hazard ratio (HR) estimates (95% confidence intervals (CIs)) of breast cancer-specific mortality associated with the percentage of tumor cell nuclei positively stained for estrogen receptor (ER) in all women (A), in white women (B), and in black women (C) with invasive breast cancer.Back to article page
