NFS was calculated using the following equation: NFS = −1.675 + 0.037 - age + 0.094 – body mass index +1.13 × impaired fasting glucose/diabetes mellitus +0.99 × aspartate aminotransferase/alanine aminotransferase ratio - 0.013 × platelet count - 0.66 × serum albumin. This evidence concerns the gene ALB and diabetes mellitus.
