Is there evidence for a benefit of statin therapy in people at low risk of vascular disease ? Interpretation: In individuals with 5-year risk of major vascular events lower than 10%, each 1 mmol/L reduction in LDL cholesterol produced an absolute reduction in major vascular events of about 11 per 1000 over 5 years. This benefit greatly exceeds any known hazards of statin therapy. Under present guidelines, such individuals would not typically be regarded as suitable for LDL-lowering statin therapy. The present report suggests, therefore, that these guidelines might need to be reconsidered. Cholesterol Treatment Trialists' (CTT) Collaborators; Lancet. 2012 Aug 11; 380(9841):581-90
