Mean deviation serum concentrations of biochemical indicators of liver tests according to the staging of NAFLD.
| Variables | Staging of NAFLD by liver biopsy | |||
|---|---|---|---|---|
| Steatosis | Steatohepatitis without fibrosis | Steatohepatitis with fibrosis | p value | |
| (n = 31) | (n = 17) | (n = 2) | ||
| AST (U/L) | 22.9 ± 12.8 | 29.9 ± 26.7 | 30.2 ± 7.6 | 0.410 |
| ALT (U/L) | 27.1 ± 15.5 | 28.2 ± 17.5 | 28.9 ± 10.3 | 0.343 |
| AP (U/L) | 75.1 ± 24.9 | 78.3 ± 20.2 | 73.1 ± 1.4 | 0.722 |
| GGT (U/L) | 24.9 ± 17.8 | 42.6 ± 27.7 | 62.4 ± 14.6 | 0.044 |
| Albumin (U/L) | 4.5 ± 0.7 | 3.9 ± 0.3 | 3.3 ± 0.2 | 0.029 |
ANOVA: mean and standard deviation. Alb: albumin; ALT: alanine aminotransferase; AP: alkaline phosphatase; AST: aspartate aminotransferase; GGT: gamma-glutamyl transpeptidase.
