In addition, increased expression of METTL18 also connected with poor DSS (HR: 2.488; CI: 1.026−6.035; P = 0.044) (Supplementary Table 6) while the expression of METTL18 demonstrated no relationship with PFI (HR: 1.114; CI: 0.736−1.687; P = 0.608) (Supplementary Table 7) in samples with HCC. This evidence concerns the gene METTL18 and hepatocellular carcinoma.
