In addition, by constructing a Cox univariate regression model based on the DSS and PFI data of HCC patients and using Cox regression for multivariate risk analysis, we confirmed that ZNF529-AS1 expression was an independent prognostic factor of DSS (p < 0.05) and PFI (p < 0.01) in HCC patients (Additional file 1: Fig. S2). Here, ZNF529 is linked to hepatocellular carcinoma.
