Study summary

This is a multicenter, randomized, double-blind, double-dummy, and positive control clinic trial which explores the efficacy and safety of ornithine aspartate granules in the treatment of non-alcoholic fatty liver disease against silymarin capsules. The hypothesis is that the ornithine aspartate granules have similar or better efficacy than the silymarin capsules.
