CtBP2 protein expression levels in HCC tissues and matched normal adjacent liver tissues were compared using the Mann-Whitney U test. The correlation between CtBP2 and GLI1 expression levels was analyzed using Spearman rank test. The Kaplan–Meier curves of HCC patients were assessed using the log-rank test. A p value of < 0.05 was considered significant. Multivariate analysis was performed using SPSS Version 17.0 software (SPSS Inc., Chicago, IL, USA). PRISM 5 software (GraphPad, La Jolla, CA, USA) was used for all other statistical analyses.
