Values are mean (SD).
Note: Alcohol consumption was available from 1,536 subjects. Statistics: Mann-Whitney test was used for continuous parameters and χ2 test for classified parameters when each fatty liver group was compared to controls (NL group). P < 0.001 for all other comparisons, except smoking (FL p = 0.209, NAFL p = 0.548 and AFL p = 0.022) and alcohol consumption (NAFL p = 0.192).
Abbreviations: NL, normal liver; FL, Fatty liver; NAFL, non-alcoholic fatty liver; AFL, alcoholic fatty liver; ALT, alanine aminotransferase; AST, aspartate aminotransferase; GT, glutamyltransferase; CRP, C-reactive protein.
