JNIadj Population: Relapse free survival analysis for JNIadj ER+ node positive tamoxifen only treated population by qRT-PCR grading: PCR-GGI low = blue and PCR-GGI high = red. The low-risk patients recurring 3 years later compared to high-risk patients (difference observed at 50% survival). Difference in relapse-free survival between two groups is summarized by the hazard ratio (HR) for recurrence with its 95% CI. All statistical tests were two-sided.
