There was a minor difference in the methRisk between patient groups stratified by prior AFP (<= 20 ng/ml versus > 20 ng/ml, P = 0.42), largest tumor size (<= 5 cm versus > 5 cm, P = 0.06), tumor number (= 1 versus >= 2, P = 0.20), and BCLC staging (0&A versus B&C, P = 0.06). Here, AFP is linked to neoplasm.
