Kaplan–Meier survival curve was utilized to analyze the effect of FOXP4-AS1 expression on the prognosis of HCC patients, and the results reported that the survival rate of HCC patients in the FOXP4-AS1 low expression group was higher than that in the FOXP4-AS1 high expression group (P < 0.05), indicating that the prognosis of HCC patient with low FOXP4-AS1 expression was better (Fig. 1K). The gene discussed is FOXP4-AS1; the disease is hepatocellular carcinoma.
