Prognosis of low- and high-risk groups in Luminal A and Luminal B samples from the TCGA and the Metabric cohort dataset. a Kaplan–Meier survival curves of low- and high-risk groups divided by eight signature genes in Luminal A and Luminal B samples from the TCGA database, respectively. The black line indicates the low-risk group, and the red line indicates the high-risk group. b Kaplan–Meier survival curves of low- and high-risk groups divided by eight signature genes in Luminal A and Luminal B samples from the Metabric cohort, respectively.
