Lobular inflammation was graded according to the number of inflammatory foci per 200 field (0 is no foci; 1 is < 2 foci per 200 × field; 2 is 2–4 foci per 200 × field); hepatocellular ballooning was graded as none (0), few balloon cells (1), and many cells/prominent ballooning (2); fibrosis stage was graded as none (Stage 0) or mild perisinusoidal fibrosis (Stage 1A); NAS: non-alcoholic fatty liver disease score.
