- 2D-SWE = two-dimensional shear-wave elastography. Diagnostic accuracy of each variable in association with fibrosis stage. The performance of the selected best cutoff values was indicated. AUC = the area under the receiver operating curve. PPV, positive predictive value; NPV, Negative predictive value; *Determined using receiver operating characteristic curve analysis
