Extensive genetic interactions (epistasis) linked to alcohol use disorder in a high-risk population.
Article in Communications biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Alcohol use disorder (AUD) is known to have a significant genetic component, yet there remains a gap between its heritability and findings from genome-wide association studies. One potential explanation for this could be genetic interactions, or epistasis, which remain largely unexplored in the context of AUD. We investigated the role of epistasis in AUD susceptibility among 742 American Indians. By analyzing 467 K variants in 3,736 genes and regulatory elements linked to AUD, we identified 97 interacting gene pairs significantly associated with AUD severity in an American Indian cohort. Five of these gene pairs: CNTNAP2-GRM8, CSMD1-DLGAP1, CSMD1-ERBB4, CSMD1-MAML2, and KCNQ5-ROBO2 - were replicated in All of Us research American Indian cohort (N = 5,037). These genes were enriched for immune system, cell adhesion, neuronal, and disease pathways. Their expressions were particularly enriched in midbrain GABAergic neurons. This large-scale epistasis study of AUD suggests that epistasis may contribute to the development of AUD.
