Fig. 4From: Comparative study of ultrasound attenuation analysis and controlled attenuation parameter in the diagnosis and grading of liver steatosis in non-alcoholic fatty liver disease patientsDisplays the ROC curves for USAT in diagnosing hepatic steatosis at different stages. The AUC for USAT in excluding hepatic steatosis (level 0) and diagnosing mild (level 1), moderate (level 2), and severe (level 3) hepatic steatosis is 0.96, 0.86, 0.81, and 0.87, respectively. ROC, receiver operating characteristic; AUC, area under the curve; CAP, controlled attenuation parameter; USAT, ultrasound attenuation analysisBack to article page
