The Study
LDL Cholesterol Reduction Variability with Different Types and Doses of Statins in Monotherapy or Combined with Ezetimibe. Results from the Spanish Arteriosclerosis Society Dyslipidaemia Registry
This study looked at what happened when people took different statins in real life — it didn't randomly assign people to drugs, it just watched what doctors prescribed and what happened. So we can say rosuvastatin was linked to bigger drops in bad cholesterol, but we can't say it caused those drops — maybe those patients were healthier or took their pills better.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
Doctors use pills called statins to lower bad cholesterol. This study looked at what happens when people take different statins or combine them with another pill.

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.
- 1Yes — rosuvastatin at the highest dose cuts cholesterol nearly twice as much as low-dose simvastatin, and adding ezetimibe makes the drop even bigger and more consistent.
- 2Rosuvastatin 40 mg lowered bad cholesterol by 58.7%.
- 3Adding ezetimibe raised that to 71.6%.
- 4Simvastatin 10 mg only lowered it by 32.5%.
- 5Men, thinner people, and those with very high starting cholesterol had smaller reductions.

Statins lower the amount of LDL cholesterol in the blood by blocking HMG-CoA reductase, an enzyme that produces cholesterol in the liver.
In adults with primary hypercholesterolemia, those who start with higher LDL cholesterol levels experience smaller reductions in LDL cholesterol after taking statins compared to those who start with lower levels.
In adults with primary hypercholesterolemia, men experience less reduction in LDL cholesterol after taking statins compared to women.
Adults with primary hypercholesterolemia who have a lower body mass index experience a smaller decrease in LDL cholesterol when taking statins compared to those with higher body mass index.
In adults with high cholesterol, taking 40 mg of rosuvastatin alone lowers LDL cholesterol by an average of 58.7%, which is a larger reduction than what is seen with 10 mg of simvastatin or other statin doses.
In adults with primary hypercholesterolemia, taking ezetimibe together with a statin leads to a larger average decrease in LDL cholesterol and more consistent results across individuals than taking a statin alone.
