Oncotype DX score is predictive of patient’s survival. A Survival plot of 3 risk groups classified by Oncotype DX (BCSS). B Hazard ratio of high and intermediate-risk groups using low-risk as baseline (BCSS). Multivariable Cox models were adjusted for tumor stage, lymph node status, breast cancer subtype (ER+HER2− or ER+HER2+), and patients’ age. C Survival plot of 3 risk groups classified by Oncotype DX (OS). D Hazard ratio of high and intermediate-risk groups using low-risk as baseline (OS). Multivariable Cox models were adjusted for tumor stage, lymph node status, breast cancer subtype (ER+HER2− or ER+HER2+), and patients’ age. P values below 0.05 were considered significant
