Fig. 4From: Dual-energy CT quantification of extracellular liver volume predicts short-term disease progression in patients with hepatitis B liver cirrhosis-acute decompensationThe ROC curves for predicting the occurrence of ACLF within 90 days. The AUC value of model was 0.893 (95% CI 0.846–0.940) in the training group (a) and 0.838 (95% CI 0.757–0.919) in the validation group (b). ROC, receiver operating characteristic; ACLF, acute-on-chronic liver failure; AUC, area under the curveBack to article page
