Further analysis for the risk-stratified patients of 5–8 score for the patients who were within and outside the AFP model showed that among 301 patients who were within AFP model (62%), the risk of 2-year HCC recurrence was 4.0% (95% CI: 0.02–0.09) in the low-risk group, 19.6% (95% CI: 0.09–0.43) in medium- risk group (p = 0.006) (Fig. 4b). Here, AFP is linked to hepatocellular carcinoma.
