Multivariate Cox proportional hazards regression analysis revealed that the expressions of ACTR3 (HR = 1.0, 95%CI: 1.01–1.1, p = 0.002), ARPC2 (HR = 1.0, 95%CI: 1.00–1.0, p = 0.016), ARPC5 (HR = 1.0, 95%CI: 1.01–1.2, p = 0.002), and the clinical stage (HR = 1.6, 95%CI: 1.31–2.0, p < 0.001) were independent prognostic biomarkers of HCC survival, as shown in the forest plots in Figures 9A–C. Here, ARPC2 is linked to hepatocellular carcinoma.
