Shared genetic architecture between stroke and blood lipids: a large-scale genome-wide cross-trait 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
backgroundBlood lipid levels are linked to stroke risk, but the genetic correlation between blood lipids and stroke is not well understood. We investigated the shared genetic architecture between blood lipids and stroke, including its subtypes, identifying common risk loci, genes, and underlying genetic mechanisms.
methodsUtilizing large-scale genome-wide association study (GWAS) summary data, we identified genetic overlap between blood lipid levels and stroke. Cross-trait pleiotropic analysis was conducted to detect shared pleiotropic loci and genes. The statistical methods employed encompassed linkage disequilibrium score regression (LDSC), stratified-LDSC (s-LDSC), heritability estimation from summary statistics (rho-HESS), pleiotropic analysis under composite null hypothesis (PLACO), cross-trait meta-analyses, colocalization analysis, multi-marker analysis of genomic annotation (MAGMA), tissue-specific enrichment analysis (TSEA), and transcriptome-wide association studies (TWASs). Bidirectional Mendelian randomization (MR) analysis was employed to explore causal associations.
resultsOur research highlights the shared genetic mechanisms between stroke and blood lipid levels. We identified 147 pleiotropic loci at a genome-wide significance level (P < 5 × 10–8). Further gene-level analysis identified 10 unique pleiotropic genes shared by stroke and lipid traits, including CUX2, SH2B3, and ICA1L. Cross-trait meta-analysis identified 28 loci, with colocalization analysis revealing two unique pleiotropic genes, PPTPN11 and SH2B3, significantly enriched in adipose, musculoskeletal, and brain tissues. Two-sample MR analysis indicated that higher HDL-C levels were associated with reduced risks of stroke and IS, while elevated TG levels increased IS risk. In a transcriptome-wide association study, we identified one previously unreported pleiotropic gene (ALDH2).
conclusionsOur research revealed a common genetic architecture between stroke and blood lipid levels, highlighting potential genetic pathways involved in both conditions.
