The effects of lowering LDL cholesterol with statin therapy in people at low risk of vascular disease: meta-analysis of individual data from 27 randomised trials

BACKGROUND: Statins reduce LDL cholesterol and prevent vascular events, but their net effects in people at low risk of vascular events remain uncertain. METHODS: This meta-analysis included individual participant data from 22 trials of statin versus control (n=134,537; mean LDL cholesterol difference 1·08 mmol/L; median follow-up 4·8 years) and five trials of more versus less statin (n=39,612; difference 0·51 mmol/L; 5·1 years).
