RNA interference versus antibody-based PCSK9 inhibition for the prevention of cardiovascular disease: a drug-target Mendelian randomization study.

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
aimsRNA interference therapies targeting liver expression of the gene proprotein convertase subtilisin/kexin type 9 (PCSK9) lower LDL-cholesterol (LDL-C) and apolipoprotein B (apoB) levels. As opposed to monoclonal antibodies, which neutralise PCSK9 circulating protein, their effect on atherosclerotic cardiovascular disease (ASCVD) outcomes is unknown. We used genetic variants in the PCSK9 locus influencing PCSK9 function or gene expression in the liver to determine whether antibodies against PCSK9 and RNA interference therapies could have comparable effects on ASCVD. METHODS AND
resultsWe performed genome-wide genotyping and RNA sequencing of 504 human liver sample and identified a genetic variant (rs472495) explaining 5.6% of liver PCSK9 gene expression to mimic lifelong RNA interference of PCSK9. We used the PCSK9 R46L variant, known to alter PCSK9 function, to model antibody-based PCSK9 inhibition. For each standard deviation decrease in apoB levels, both variants were similarly associated with coronary artery disease risk: (odds ratio [OR] = 0.40, 95% confidence interval [CI]: 0.31-0.51, P = 3.7e-13 for rs472495 which affects liver PCSK9 expression) and (OR = 0.48, 95% CI: 0.43-0.55, P = 1.3e-28 for R46L which affects protein levels). Comparable effects of these two genetic inhibition approaches were observed for aortic stenosis, heart failure, ischemic stroke, Type 2 diabetes and glycemic traits as well as non-alcoholic fatty liver disease and liver enzymes.
conclusionFor a given reduction in apoB levels, genetically predicted reductions in PCSK9 function (mimicking PCSK9 neutralizing antibodies) and liver PCSK9 gene expression levels (mimicking PCSK9 RNA interference) were comparably associated with a lower risk of coronary artery disease. These genetic data suggest that LDL-C/apoB reductions may provide cardiovascular benefits, regardless of how PCSK9 function is inhibited.
