..., the degree of liver fibrosis was not quantified in the current study. Therefore, it is possible that mild degrees of fibrosis (grades 0 to 3) could be present in the current study [ 30 ]. Yeh et al. [ 30 ] reported that the mean elastic modulus values generally increased with increasing fibrosis grades...
