Table 2. Correlations between Estimated LS Values Assessed by VTQ and by S-Shearwave in Subgroups of Subjects.

Subgroup of Subjects	Correlation VTQ and S-Shearwave Values*
All	r = 0.78, p < 0.0001
F ≤ 2	r = 0.82, p < 0.0001
F3	r = 0.78, p < 0.0001
F4	r = 0.73, p < 0.0001

Cut-offs used in classification of liver fibrosis was F ≥ 2 (7.9 kPa), F ≥ 3 (8.8 kPa), and F = 4 (11.7 kPa) according to transient elastography (12). *Spearman r correlation coefficient. LS = liver stiffness, S-Shearwave = S-Shearwave elastography, VTQ = Virtual Touch Quantification
