JARID2 and neoplasm: In training cohort (Supplementary Figure 1 and Supplementary Table 1), the results showed that, in addition to tumor numbers, capsular formation, microvascular invasion, TNM stage and BCLC stage, high JARID2 expression in HCC tissues was also found to be a significant independent prognosis factor for disease-free survival (DFS) (HR 1.641; 95% CI: 1.294 to 3.102; P = 0.017; Table 2) and overall survival (OS) (HR 1.873; 95% CI: 1.108 to 3.845; P = 0.041; Table 3).
