Kaplan-Meier analysis of MFS for SIPA1 and RRP1B SNPs on stratified patient populations. (a) RRP1B rs9306160 in node-negative, estrogen receptor (ER)-positive patients; (b) RRP1B rs9306160 in node-positive, ER-positive patients; (c) SIPA1 rs2448490 in node-negative, ER-positive patients; (d) Combination of SIPA1 rs2448490 and RRP1B rs9306160 in node-negative, ER-positive patients. LN = lymph node; MFS = metastasis-free survival.
