TT genotype of rs1271572 was associated with worse survival in breast cancer. Kaplan–Meier breast cancer-free survival was applied to determine the prognosis A) among patients with the three genotypes (GG, GT and TT) of rs1271572; B) between ERβ–positive and ERβ–negative patients; C) between ERβ–negative and ERβ–positive patients in the ER- subgroup, and D) between ERβ–negative and ERβ–positive patients in the Her + patients. The p values were determined using the log-rank test; a significant difference was assumed for p < 0.05.
