No significant differences were found in alpha-fetoprotein concentrations within the total HCC population (p = 0.834) or when HCC stages were grouped as 0–A (23.1 (4.5–79.8) ng/mL) and B–C–D (19.9 (4.7–438.6) ng/mL) (p = 0.704), as performed for the analysis of PN. Here, AFP is linked to hepatocellular carcinoma.
