Then, according to multivariate analysis, only CFD (HR = 0.84, p = 0.0327), PPARG (HR = 0.80, p = 0.0478), CD27 (HR = 0.75, p = 0.0001), PSMB9 (HR = 0.73, p = 0.00299), and SELL (HR = 0.77, p = 0.0062) were still significantly positively associated with OS as potentially independent prognostic factors in BC patients (Table S8). The gene discussed is PPARG; the disease is breast cancer.
