Furthermore, the recurrence-free survival (RFS) and overall survival (OS) curves were drafted by Kaplan-Meier analysis and verified by the log-rank test, which demonstrated that HCC patients with relatively low expression of lnc-ZEB2-19 had poorer RFS and OS than those with high lnc-ZEB2-19 expression (Fig. 1F, G). The gene discussed is ZEB2; the disease is hepatocellular carcinoma.
