Figure 4From: Simultaneous CXCL12 and ESR1 CpG island hypermethylation correlates with poor prognosis in sporadic breast cancer Kaplan-Meier curves for time to breast cancer progression according to CXCL12 methylation status. Kaplan-Meier estimates are shown for overall survival using (A) ESR1 methylation, (B) CXCL12 island 4 methylation, and for metastasis-free survival using (C) ESR1 methylation, (D) CXCL12 island 4 methylation. Symbols on the graph lines represent censored data; p values are given for log rank tests.Back to article page
