Univariate Cox analysis showed that high expression of YY1 was correlated with poor progress free interval (PFI)of BLCA, while low expression of YY1 was correlated with poor OS and poor disease-specific survival (DSS) of KIRC and poor PFI of OV (Supplementary Tables S1–S12). The gene discussed is YY1; the disease is bladder transitional cell carcinoma.
