“…We identified 24 studies [ 20 , 33 , 35 , 38 , 39 , 41 , 43 , 44 , 45 , 46 , 51 , 61 , 64 , 71 , 72 , 73 , 75 , 85 , 87 , 88 , 89 , 90 , 91 , 92 , 93 ] and three meta-analyses [ 66 , 81 , 83 ] that investigated the effects of olive oil-based ILE on liver function ( Table 5 ). Findings have varied across studies, and no clear pattern of effect of olive oil-based ILE on markers of liver function (sometimes called liver function tests) such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin (total or conjugated) or on biliary tract function markers such as alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) have been discerned.…”
