Discussion The assessment of therapeutic agents for non-alcoholic steatohepatitis is a complex process. Because you can find no validated biomarkers of response to treatment, one must depend on histologic assessment of a liver-biopsy specimen for this function.17 A decrease in their severity happens with amelioration of the condition; however, the severity of these components could also decrease with progression of fibrosis to cirrhosis.20,21 To develop an final result that was both quantifiable and clinically relevant, the requirements of a noticable difference in ballooning and no worsening of fibrosis were put into the necessity of a reduction in the non-alcoholic fatty liver disease activity score for the principal outcome.
