Furthermore, to further investigate the role of INHBA in breast cancer prognosis, we verified that INHBA was negatively correlated with OS [HR (95%CI) = 1.84 (1.3–2.59), p = 0.00044] and RFS [HR (95%CI) = 1.66 (1.08–2.56), p = 0.019] using pan-cancer RNA-seq data from the Kaplan–Meier plotter database (Figures 3H,I). Here, INHBA is linked to breast carcinoma.
