  1. Cutoff critical cutoff value, AUC area under the receiver operating characteristic curve, PPV positive predictive value, NPV negative predictive value
  2. AUC* adjusted for inflammation and ballooning
  3. S ≥ S1 fatty liver, S ≥ S2 moderate steatosis or higher severity, S = S3 severe steatosis
