Interestingly, the Kaplan‐Meier curve indicated that the high MAOA mRNA expression group had a better survival outcome, with a hazard ratio of 0.61 (95% CI: 0.41‐0.93) (Logrank P = .019; Figure 3), indicating that the downregulated MAOAmRNA correlated with a poor prognosis of HCC patients. Here, MAOA is linked to hepatocellular carcinoma.
