High PRKRA expression levels predict poor prognosis of HBV-related HCC patients. A, B Kaplan–Meier analysis of overall survival (A) and disease-free survival (B) of HBV-related HCC patients based on PRKRA expression (n = 145). The median of PRKRA expression levels was used as the cutoff value for grouping C, D Univariate analysis (C) and multivariate COX regression models (D) including 6 parameters (PRKRA expression, serum AFP level, sex, age, TNM-stage and pathologic grade) were employed to explore risk factors for HBV-related HCC. Symbols indicate Hazard ratio, and bars indicate 95% CIs in forest plots. Uni: Univariate; Mut: multivariate; CI: confidence interval
