First-line GLP-1 RA initiation is associated with greater HbA1c reduction compared to metformin in both patients with prediabetes and diabetes.
GLP-1 RA is more effective than metformin at lowering HbA1c levels in both prediabetes and diabetes. This makes it a potent option for achieving glycemic targets, though adherence should be monitored.
GoodSupportsHIGH confidence
Compared to metformin, GLP-1 RA was associated with greater HbA1c reduction (prediabetes: -2.59 mmol/mol 95% CI: -3.10 to -2.09, diabetes: -3.79 mmol/mol, 95% CI: -5.28 to -2.30).
Why this rating
Large nationwide cohort study with rigorous matching and adjustment.

- In drug-naive patients with prediabetes, initiating GLP-1 RA as first-line therapy significantly reduces the 1-year risk of requiring additional glucose-lowering medication compared to metformin, but is associated with a significantly higher risk of treatment nonadherence.Good
- In drug-naive patients with diabetes, initiating GLP-1 RA as first-line therapy reduces the 1-year risk of requiring additional glucose-lowering medication compared to metformin, with no significant difference in adherence rates.Good
