Impact of Evolocumab on LDL-Cholesterol and Cardiovascular Outcomes in Patients With Established CVD: Systematic Review and Meta-Analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAtherosclerotic cardiovascular disease is a leading cause of morbidity and mortality, and many high-risk patients fail to reach LDL-cholesterol (LDL-C) targets on statins alone. Evolocumab, a PCSK9 inhibitor, offers potent LDL-C lowering, but a synthesis of its lipid and clinical benefits in secondary prevention is needed.
methodsWe conducted a systematic review and meta-analysis of randomised controlled trials evaluating evolocumab in adults with established cardiovascular disease. PubMed, Embase, Scopus, Cochrane CENTRAL, and ClinicalTrials.gov were searched through April 2025. Outcomes included lipid parameters, major adverse cardiovascular events (MACE), individual cardiovascular endpoints, and safety, with pooled risk ratios (RR) and mean differences calculated using random-effects models.
resultsNine trials enrolling 67,662 patients were included. Evolocumab significantly reduced LDL-C (mean difference -57.73 mg/dL), total cholesterol (-52.27 mg/dL), triglycerides (-21.21 mg/dL), and lipoprotein(a) (-10.99 mg/dL), while increasing HDL-cholesterol (3.69 mg/dL). Evolocumab was associated with lower MACE (RR 0.53; 95% CI 0.40-0.71), though this estimate should be interpreted cautiously given heterogeneity in endpoint definitions and study designs. Myocardial infarction (RR 0.74) and coronary revascularisation (RR 0.80) were significantly reduced, while cardiovascular mortality and stroke showed no statistically definitive reduction. Serious adverse events and neurocognitive effects were comparable between groups, though injection-site reactions were more frequent with evolocumab.
conclusionIn patients with established cardiovascular disease, evolocumab provides substantial lipid lowering and reduces ischemic events without major safety concerns, supporting its use as an adjunct to statin therapy in secondary prevention.
