The Claim

Genetically predicted intake of low-calorie drinks is nominally associated with a higher risk of cardioembolic stroke, with an odds ratio of 1.71 (95% confidence interval: 1.12–2.63), and this association shows attenuation after adjustment for body mass index, suggesting potential influence by adiposity or metabolic factors.

In plain English

Drinking more low-calorie drinks might be linked to a higher chance of a certain kind of stroke, but it's possible that this link comes from body weight or other metabolic factors instead.

See the scientific wording

Genetically predicted intake of low-calorie drinks is nominally associated with a higher risk of cardioembolic stroke, with an odds ratio of 1.71 (95% CI: 1.12–2.63), though this association may be influenced by adiposity or metabolic factors given attenuation after adjustment for BMI.

What the research says

1 study

  1. Study: Genetically Predicted Artificial Sweeteners and Stroke Susceptibility: A Multivariable Mendelian Randomization Study.

    The study found that people genetically likely to drink more low-calorie drinks had a higher chance of a certain type of stroke, and this matches the claim. It also agrees that body weight might play a role in this link.
