The Study
Risk and effect modifiers for poor glycemic control among the chinese diabetic adults on statin therapy: the kailuan study
This study watched two groups of people with diabetes over time — some who started taking statins and some who didn’t — to see what happened to their blood sugar. It found that people on statins were more likely to have worse blood sugar control, but because they weren’t randomly assigned to the groups, we can’t say for sure that the statins caused the problem.

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1The effect is small but meaningful, especially over time and in thinner individuals, suggesting statins may slightly worsen diabetes control.
- 2Statin users had a 0.20% higher HbA1c and a 69% higher chance of needing stronger diabetes medicine or developing high blood sugar compared to nonusers.
