Table 4 Cox proportional hazards analysis for predicting survival in the subgroups according to risk scores

From: Novel biomarker-based model for the prediction of sorafenib response and overall survival in advanced hepatocellular carcinoma: a prospective cohort study

Risk group HR (95% CI) P
Intermediate risk vs. low risk 2.529 (1.120–5.707) 0.025
High risk vs. low risk 6.577 (3.419–12.655) < 0.001
  1. Risk groups according to risk scores: low-risk group, score ≤ 5; intermediate-risk group, score 6; high-risk group C, score ≥ 7
  2. Abbreviations: HR hazard ratio, CI confidence interval
