Druggable genome-wide Mendelian randomization analysis identifies potential treatment targets in vascular dementia.

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
backgroundThere are currently no US Food and Drug Administration-approved treatments for vascular dementia (VaD). Genome-wide approaches have successfully identified druggable targets and treatments for various disorders. In this study, we performed druggable genome-wide two-sample Mendelian randomization (2SMR) analysis to identify possible treatment targets for VaD.
methods2SMR analyses were used to estimate the causal effects of druggable gene expression on VaD risk. The exposure variables were significant cis-expression quantitative trait loci (eQTLs) and cis-protein quantitative trait loci (pQTLs) in the cerebrospinal fluid (CSF), brain, and plasma. The main outcome variable was genetic VaD risk, based on the Mega Vascular Cognitive Impairment and Dementia Consortium genome-wide association study. 2SMR analysis examined the causal relationship between eQTLs/pQTLs and imaging markers of VaD. A phenome-wide 2SMR analysis explored the relationships between significant druggable genes and phenotype summary statistics derived from the UK Biobank. False discovery rate (FDR)
resultsA total of 12,224 druggable genes were identified from the Drug-Gene Interaction Database (DGIdb) and associated papers. Of these, the 2SMR analysis identified four FDR-significant genes in the pQTL analysis, with none identified among the eQTLs. In the CSF, DISCUSSION: This study identified four potential drug targets for VaD, using a 2SMR analysis approach. Two genes,
