In the GSE13507 cohort based on univariate Cox analysis, SLC12A8 overexpression was predicted poor cancer-specific survival in BC patients (HR = 1.2338, p < 0.01); however, it was not an independent factor by multivariable Cox analysis (HR = 0.6537, p = 0.2715) (Table 3). Here, SLC12A8 is linked to breast cancer.
