1.13 × impaired fasting glycaemia or DM (yes = 1, no = 0) + 0.99 ×
AST/ALT ratio − 0.013 × platelet (×109/L) − 0.66 × albumin (g/dL)
[14]. The cut-off points of the NFS used to categorise fibrosis were:
b−1.455, −1.455 to 0.676, and N0.676 for low indeterminate and
high probability for advanced fibrosis, respectively [14]. Calculation of
the BARD score was also performed; the BARD score was a 4 point
score derived from the weighted sum of three variables (BMI N 28 =
one point, AST/ALT ratio N 0.8 = two points, diabetes = one point)
where a score of two or more suggestive of advanced fibrosis [13].
Similarly, AST/ALT ratio more than 0.8 itself has been suggested to be
useful in predicting advanced fibrosis [21].
