Fig. 1 Representation of the distribution of variables: 50% of values are comprised within the box (between the 25th and 75th percentile), and the horizontal bar gives the median; 80% of values are comprised between the extremities of vertical bars (between the 10th and 90th percentile), and the extreme values are represented as individual points. 2, No severe fibrosis; ▨, severe fibrosis.

Fig. 2 Correlation between serum ferritin and AST values. Spearman test: ρ = 0.628; P < 10−4. The horizontal and vertical bars represent the chosen thresholds for serum ferritin = 1000 μg/L and AST = 1 ULN.

Fig. 3 Decision tree using the three variables (serum ferritin, hepatomegaly, and serum AST) selected by multivariate analysis. The term fibrosis refers to severe (stage 3 or 4) fibrosis.
