Fig. 2From: Prognostic factors affecting postoperative survival of patients with solitary small hepatocellular carcinomaThe proposed prognostic model successfully stratified risk for survival prediction of patients with sHCC (log-rank test). Using this model, these sHCC patients were stratified into three groups: low risk, n = 142; intermediate risk, n = 159; high risk, n = 34. a The OS curves of the three groups were significantly different (P < 0.001). b The RFS curves of the three groups were significantly different (P < 0.001)Back to article page
