A: Receiver operating characteristic curve of the fatty liver index for identifying undiagnosed non-alcoholic fatty liver disease in lean participants with a normal waist circumference; B: Receiver operating characteristic curve of the waist-height ratio for identifying undiagnosed non-alcoholic fatty liver disease in lean participants with a normal waist circumference. ROC: Receiver operating characteristic; FLI: Fatty liver index.
