The Claim

In adults with type 2 diabetes, once-weekly exenatide at a dose of 2 mg reduces the risk of all-cause mortality by 14% (hazard ratio 0.86, 95% CI 0.77–0.97) over a median follow-up of 3.2 years, based on data from a randomized controlled trial of 14,752 participants, with a more pronounced effect observed in individuals without preexisting heart failure, where mortality risk is reduced by 21%, supporting the role of GLP-1 receptor agonists in cardiovascular risk reduction strategies.

In plain English

A weekly diabetes shot called exenatide may help people with type 2 diabetes live longer, especially if they don’t already have heart failure.

See the scientific wording

Once-weekly exenatide at a dose of 2 mg reduces the risk of all-cause death by 14% in adults with type 2 diabetes, with a hazard ratio of 0.86 (95% CI 0.77–0.97), based on data from a randomized controlled trial involving 14,752 participants followed for a median of 3.2 years. This effect is driven primarily by benefits in patients without preexisting heart failure, where mortality risk is reduced by 21%. The finding supports the use of GLP-1 receptor agonists as part of cardiovascular risk reduction strategies in type 2 diabetes.

    The study tested the same drug and dose as claimed and found it lowered the risk of death, especially in people without heart failure, just like the claim says.
