The Study
Relative contributions of statin intensity, achieved low-density lipoprotein cholesterol level, and statin therapy duration to cardiovascular risk reduction in patients with type 2 diabetes: population based cohort study
This study looked at real-world health records of people with type 2 diabetes who took statins and watched what happened to their heart health over time. It can show that longer statin use is linked to lower heart risks, but it can't prove that the statins themselves caused the benefit because other healthy habits might also play a role.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
For grown-ups with type 2 diabetes, taking statin pills for a longer time helps keep their heart healthier more than how strong the pill is or how low their cholesterol gets.

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.
- 1Yes, this is important—staying on statins long-term can meaningfully reduce heart attacks and strokes in people with diabetes.
- 2Taking statins for 18+ months lowers heart problem risk by 30%.
- 3Taking them for 3+ years lowers it by 36%.
- 4Stronger pills lower risk by 28% vs weak ones.
- 5Lower cholesterol also helps, but time on the pill matters most.
