Figure 3 presents the OS curves. In this study, we found that remarkably increased ALKBH1 (p = 0.0099) and ALKBH4 (p = 0.028) expression were correlated with a bad prognosis (Fig. 3). Then, we also evaluated the DFS of patients with HCC. We observed that similarly, high expression levels of ALKBH2 (p = 0.0085) and ALKBH4 (p = 0.00041) were correlated with a poor DFS (Fig. 4). This evidence concerns the gene ALKBH4 and hepatocellular carcinoma.
