Fig. 4From: Performance of spleen stiffness measurement by 2D-shear wave elastography in evaluating the presence of high-risk varices: comparative analysis of idiopathic portal hypertension versus hepatitis B virusArea under the receiver operating characteristic curves for the prediction of the presence of HRV in IPH (a) and HBV-infected patients (b). Note: LS, liver stiffness; SS, spleen stiffness; SS/LS, spleen stiffness-to-liver stiffness ratio; PH risk score, portal hypertension risk score; LSPS, liver stiffness spleen-diameter-to-platelet-ratio scoreBack to article page
