The Kaplan–Meier plotter revealed that breast cancer patients with upregulated INHBA demonstrated worse prognosis using probe set 20496_at [Figures 3B–D; OS HR (95%CI) = 1.5 (1.19–1.88), p = 0.00045; RFS HR (95%CI) = 1.11 (0.99–1.25), p = 0.08; DMFS HR (95%CI) = 1.38 (1.09–1.75), p = 0.0079]. This evidence concerns the gene INHBA and breast cancer.
