This trial is expected to enroll 138 MAFLD patients in one clinical center, who will be randomly divided into a placebo group and a Ganzhixiao capsule group in a 1:1 ratio. There will be 69 patients in the Ganzhixiao group and 69 patients in the placebo group. Administer Ganzhixiao capsules or mimetics separately, intervene for 16 weeks, and compare the liver fat content、 ALT、 Changes in indicators such as cytokeratin 18 fragment, FIB-4 score, and LSM score. Among them, MRI-PDFF is the main efficacy evaluation index to evaluate the clinical efficacy of Ganzhixiao capsules in the treatment of MAFLD.

All participants in the trial were required to have a low-fat diet and engage in aerobic exercise for 150 minutes per week.
