Figure 1 Box and whisker plots of stiffness values in patients at METAVIR stage F0-F1 and in healthy subjects. Box plots show interquartile range (box), median (line within box), range (whisker) and outliers (circle). Median values (IQR) and P values of differences are given. A: Point shear wave elastography (PSWE) values; B: Transient elastography (TE) values.

Figure 3 Receiver-operating characteristic curves for different fibrosis thresholds. The performance of point shear wave elastography (PSWE) was compared to that of transient elastography (TE). P values for differences between areas under the curve are given. A: F0-F1 vs F2- F4 (F≥ 2); B: F0-F2 vs F3-F4 (F≥ 3); C: F0-F3 vs F4 (F = 4).
