Serum ALT | 53 | 79.5 | 40.7 | 49.2 | 73.3 |
67 | 71.8 | 59.3 | 56.0 | 74.4 | |
100 | 41.0 | 79.6 | 59.3 | 65.2 | |
Serum AST | 30 | 84.6 | 40.7 | 50.8 | 78.6 |
48 | 69.2 | 77.8 | 69.2 | 77.8 | |
65 | 43.6 | 90.7 | 77.3 | 69.0 | |
Serum GGT | 49 | 84.6 | 42.6 | 51.6 | 79.3 |
84 | 64.1 | 70.4 | 61.0 | 73.1 | |
109 | 46.2 | 77.8 | 60.0 | 66.7 |
ALT, alanine aminotransferase; AST, aspartate aminotransferase; GGT, gamma glutamyl transpeptidase; NASH, non-alcoholic steatohepatitis; PPV, positive predictive value; NPV, negative predictive value.
* Cut-off with high sensitivity, highest overall accuracy and high specificity were presented.
