Regional Heterogeneity of the Results of Glucagon-Like Peptide 1 Receptor Agonist Trials in Type 2 Diabetes: A Reanalysis of Individual Participant Data

Diabetes CarePublished Systematic review and meta-analysis of individual participant data from randomised controlled trials

Authors' conclusion

This study does not suggest any regional heterogeneity of GLP-1RA efficacy in MACE. However, a higher baseline risk and lower development status were associated with a greater benefit of these drugs.

Study context

Population
Patients with T2D in international RCTs of GLP-1 RA vs placebo with major cardiovascular events (MACE) as primary end point (Medline and Cochrane Library, inception to 30 June 2020)
Participants
45,426 patients6 RCTs
Comparison
GLP-1 RA vs placebo, by region
Outcome
MACE
