The Claim

Statin therapy is associated with a 10% relative increase in worsening glycaemic control among individuals with pre-existing diabetes, as defined by an HbA1c rise of at least 0.5%, treatment escalation, or diabetes-related complications, with a greater effect of 24% observed under high-intensity statin regimens.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

1 study reviewed

In plain English

Taking statins might make blood sugar control worse for people who already have diabetes, especially if they're on a stronger dose.

See the scientific wording

Statin therapy causes a 10% relative increase in worsening glycaemic control among people with pre-existing diabetes, defined by HbA1c rise ≥0.5%, treatment escalation, or diabetes-related complications, with a greater effect of 24% observed under high-intensity regimens.

What the research says

1 study

Study: Effects of statin therapy on diagnoses of new-onset diabetes and worsening glycaemia in large-scale randomised blinded statin trials: an individual participant data meta-analysis
The study found that statins slightly increase the risk of blood sugar worsening in people who already have diabetes, especially with stronger doses, just like the claim says.
