Effectiveness of GLP-1 Receptor Agonists in T2DM and Obesity

Summary

This retrospective cohort study evaluates the impact of GLP-1 receptor agonists on BMI and blood glucose levels in patients with T2DM and obesity. Using difference-in-difference analysis, it compares GLP-1RA with other second-line antidiabetic treatments over a 24-month period. Findings indicate significant BMI reduction and improved glycaemic control in the GLP-1RA group, suggesting its preference for obese T2DM patients not responsive to metformin monotherapy.

Methodology

Data were collected retrospectively from patients receiving GLP-1RA or other second-line treatments. Analysis used linear mixed-effect regression with inverse probability weighting to adjust for confounders.

Interventions

Interventions included GLP-1RAs such as exenatide, liraglutide, and semaglutide administered over 24 months.

Key Findings

GLP-1RA treatments led to greater reductions in BMI and blood glucose compared with other therapies, supporting their use for T2DM with obesity.

Comparison with other Studies

The findings align with previous RCTs and observational studies indicating sustained BMI and glucose improvements with GLP-1RA.
