statins decreases LDL cholesterol
In plain terms: Do statins lower LDL cholesterol?
Part of: 💊 statins
Unambiguously yes — this is a direct, dose-dependent pharmacologic effect quantified across thousands of patients.
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."

The evidence (9)
| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Jones STELLAR 2003 · Am J Cardiol | RCT | supports | high | STELLAR head-to-head: across doses, statins lowered LDL 26-63% in a dose-dependent manner (rosuvastatin most potent), with consistent reproducible reductions. |
| Zhang 2020 · Biomed Res Int | meta-analysis | supports | high | Network meta-analysis of 50 RCTs directly compared 7 statins and quantified their dose-dependent LDL-cholesterol lowering. |
| Sabatine 2018 · JAMA Cardiology | meta-analysis | supports | high | Meta-analysis showed per 1-mmol/L LDL-C lowering yielded ~22% relative reduction in major vascular events, confirming statins' LDL-lowering efficacy and its clinical linkage. |
| Liu 2026 · JACC Asia | RCT | supports | moderate | Multicenter double-blind RCT of red yeast rice (natural statin, monacolin K) significantly lowered LDL cholesterol versus placebo. |
| Kritharides 2015 · Future Cardiol | meta-analysis | supports | high | CTT individual-data meta-analysis of 174,000 participants in 27 trials confirmed statins lower LDL-C with ~21% event reduction per mmol/L in both sexes. |
| Gencer 2020 · Lancet | meta-analysis | supports | high | Meta-analysis of RCTs in older patients confirmed statin LDL-lowering reduced LDL-C and translated to major vascular event reduction. |
| Abbas 2026 · Future Cardiol | meta-analysis | supports | moderate | Meta-analysis found pitavastatin (with/without ezetimibe) significantly reduced LDL cholesterol in hypercholesterolemia and mixed dyslipidemia. |
| Heart Protection Study 2002 · Lancet | RCT | supports | high | HPS: simvastatin 40mg lowered LDL by ~1.0 mmol/L (~39 mg/dL) versus placebo across 20,536 participants, a large independently observed reduction. |
| Cholesterol Treatment Trialists 2005 · Lancet | meta-analysis | supports | high | CTT confirmed a robust per-mmol/L LDL-lowering effect of statins across 14 trials, the basis for the per-mmol/L event-reduction relationship. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
