AFP and hepatocellular carcinoma: Patients with HCC and AFP model of 0–2 points tended to exhibit lower 5-year survival rate (68.0%) than low-risk non-HCC patients (p = 0.082), whereas survival of HCC patients with AFP model of 3–4 points (69.9%) and >4 points (50.0%) was similar to that observed for moderate-risk (p = 0.469) and high-risk (p = 0.521) non-HCC patients, respectively (Supplementary Fig. 3).
