Fig. 1From: Artificial neural network model to predict post-hepatectomy early recurrence of hepatocellular carcinoma without macroscopic vascular invasionSchematic representation of the ANN model developed to predict PHER in HCC patients without macroscopic vascular invasion. The blue lines represent synaptic weights < 0, while the grey lines represent synaptic weights > 0. Abbreviations: HCC, hepatocellular carcinoma; ANN, artificial neural network; PHER, post-hepatectomy early recurrence; HBV-DNA, hepatitis B virus DNA load; GGT, γ-glutamyl transpeptadase; AFP, α-fetoprotein; MVI, microvascular invasionBack to article page
