Abstract

GLP-1 receptor agonist (GLP-1RA) use was associated with a lower risk of liver fibrosis progression in patients with type 2 diabetes and early-stage metabolic dysfunction-associated steatotic liver disease.

  • GLP-1RA users had an incidence rate of 3.25 per 100 person-years for fibrosis progression, compared to 4.29 for those using dipeptidyl peptidase-4 inhibitors (DPP-4i).
  • The hazard ratio for fibrosis progression in GLP-1RA users was 0.75, indicating a 25% reduction in risk compared to DPP-4i users.
  • Risk reduction with GLP-1RA was consistent across various subgroups, including those with low baseline fibrosis scores and lower body mass index.
  • No significant differences in secondary liver-related outcomes were observed between GLP-1RA and DPP-4i users.
