Fig. 3From: A novel imaging index for predicting adverse progression in acute-on-chronic liver failure related to hepatitis B virus: the low erector spine indexROC for evaluating mortality in patients with HBV-ACLF. The areas under the ROC (95% CI) of the ESI and SMI were 0.755 (0.536–0.973) and 0.773 (0.563–0.983), respectively. ESI: erector spine index. SMI: skeletal muscle indexBack to article page
