Metabolic effects of GLP-1 receptor agonists in rheumatology patients and inflammatory outcomes: a single-centre retrospective cohort

RMD OpenPublished Retrospective cohort study

Authors' conclusion

GLP-1RAs were associated with meaningful metabolic improvements in patients with rheumatic diseases, with a favourable safety profile.

Study context

Population
