PROZ and hepatocellular carcinoma: Kaplan–Meier analysis showed that the overall survival time of patients with high PROZ expression was significantly increased compared with the low expression group (Figure 3C), and the progression-free survival time was also significantly prolonged (Figure 3D), suggesting that PROZ is closely related to the prognosis of HCC, and patients with high PROZ expression indicate a better prognosis.
