In training cohort, high JARID2 expression in HCC tissues positively correlated with tumor number (P = 0.002), microvascular invasion (P = 0.001), Edmondson-Steiner grade (P = 0.004), HCC subtype (P = 0.007), TNM stage (P = 0.042) and BCLC stage (P = 0.049) (Table 1). This evidence concerns the gene JARID2 and hepatocellular carcinoma.
