AFP and hepatocellular carcinoma: After including dichotomous value of LS into analysis (model 2), a higher baseline AFP level (subdistribution hazard ration [SHR]: 1.701, p = 0.040) and significant LS > 1.5 m/s (SHR: 2.000, p = 0.027) could independently predict HCC recurrence after RFA (Table 4).
