POGK and hepatocellular carcinoma: Kaplan-Meier survival analysis showed that high POGK expression correlated with a poor prognosis in HCC patients in terms of overall survival (OS) (p = 0.0018), progression-free survival (PFS) (p = 0.0087), relapse-free survival (RFS) (p = 0.045), disease-specific survival (DSS) (p = 0.014) (Figure 4A–D).
