As expected by stratifying subjects according to the NAFLD fibrosis score, individuals classified as at high or intermediate probability of liver fibrosis were older (P<0.0001), had higher BMI (P<0.0001) and AST/ALT ratio (P<0.0001), lower platelet count (P<0.0001) and albumin levels (P<0.0001), and were more likely to have elevated fasting glucose (P<0.0001) and insulin (P = 0.009) or IFG/IGT/type 2 diabetes (P<0.0001) as compared with those at low probability of liver fibrosis. This evidence concerns the gene GPT and type 2 diabetes mellitus.
