Description

Rodriguez et al reported 2 scores for screening an adult for non-alcoholic fatty liver disease (NAFLD) based on practical clinical measures. This can help to identify a patient who may benefit from a more complete evaluation. The authors are from the University of California San Francisco, University of California Berkley, Wake Forest University and University of California San Diego.

total score =

= SUM(points for all of the parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 28

• A score >= 20 has a sensitivity of 80%, specificity of 60% and post-test probability of > 8%.

 

Performance:

• The area under the ROC curve is 0.78 for validation and 0.70 for validation cohorts.
