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.

For patients with prediabetes, GLP-1 RA is more effective than metformin at preventing the need for extra diabetes medications over one year. However, patients are more likely to stop taking GLP-1 RA than metformin. Clinicians should proactively manage expectations regarding side effects and adherence to maximize the benefit.

Why this rating

Large nationwide cohort study (n=3556) with rigorous matching and adjustment, though observational design limits causal inference compared to RCTs.
