The results of overall survival analysis indicated that the expression levels of FANCD2 (p = 0.000193, HR = 2.689), CS (p = 0.00747, HR = 1.978) and SLC1A5 (p = 0.000123, HR = 2.738) affected the survival of HBV-related HCC patients, the survival advantage of low-expression groups was considerably greater as opposed to that of high-expression groups (Figure 2). Here, CS is linked to hepatocellular carcinoma.
