Triglyceride-Glucose-BMI Index in Non-Alcoholic Fatty Liver Disease (NAFLD)

Parameters:

(1) serum triglyceride in mg/dL

(2) fasting plasma glucose in mg/dL

(3) body mass index (BMI) in kg per square meter

triglyceride-glucose index =

= LN(((serum triglyceride) + (fasting glucose))/2)

triglyceride-glucose-BMI index =

= (triglyceride-glucose index) * (BMI)

Interpretation:

• The risk of non-alcoholic fatty liver disease increases as the index increases.

Performance:

• In nonobese patients the index had an area under the ROC curve of 0.835 for detected NAFLD.
