DNA methylation is associated with von Willebrand factor and coagulation factor VIII plasma levels: the atherosclerosis risk in communities study.
Article in Clinical epigenetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLimited information is available on how DNA methylation of cytosine-phosphate-guanine (CpG) sites across the genome regulate circulating von Willebrand Factor (VWF) and factor VIII (FVIII) levels.
methodsWe performed an epigenome-wide association study to examine the association of leukocyte DNA methylation levels at 483,735 CpG sites with VWF antigen plasma levels and FVIII activity in 2,597 Black and 1,011 White participants from the Atherosclerosis Risk in Communities (ARIC) study. VWF antigen levels and FVIII activity were measured at the baseline exam, while DNA methylation was measured with the Infinium HumanMethylation450 BeadChip array at visit 2 or 3. Discovery analysis was performed in the Black population, with replication in the White population.
resultsWe identified 55 and 46 significant CpG sites associated with VWF and FVIII (P < 1.03 × 10
conclusionWe identified novel epigenetic associations with VWF and FVIII levels at the NBEAL2 and B3GALT4 loci. NBEAL2 is critical for the biosynthesis of platelet alpha granules, which store proteins that enable platelet adhesion initiation, including VWF while B3GALT4 is involved in glycosylation of glycoproteins like VWF and FVIII.
