  1. HBs antigen: hepatitis B surface antigen; AFP: alpha-fetoprotein.
  2. #The median expression level was used as the cutoff. Low CCAT1 expression in each of the 66 patients was defined as a value below the 50th percentile. High CCAT1 expression in each of the 66 patients was defined as a value above the 50th percentile.
  3. *For analysis of correlation between the expression levels of CCAT1 and clinical features, Pearson chi-square tests were used. Results were considered statistically significant at p < 0 .05.
