Development of a comprehensive GWAS atlas for chicken breeds.
Article in BMC bioinformatics, 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
Modern poultry breeding requires integrated genomic and phenotypic data to optimize production traits, yet comprehensive resources remain fragmented and often inaccessible. We developed a comprehensive electronic Genome-Wide Association Studies (GWAS) Atlas for chicken breeds that consolidates genomic data with phenotypic information from both commercial and heritage breeds. This web-based platform addresses critical gaps in existing databases through a unified, cross-referenced system linking more than 2,500 SNPs and other DNA alterations to 454 documented traits across diverse chicken breeds. The Atlas features four integrated portals: breed profiles with visual catalogs, trait-based breed searches using hierarchical classification, genomic information with DNA alterations and affected genes linked to specific traits, and advanced search functionality. A key innovation is the platform’s ability to reveal previously hidden cross-source genetic associations, such as connecting the GJA5 gene’s roles in both egg production and feather coloration. This publicly accessible resource provides breeders and researchers worldwide with comprehensive tools for informed decision-making in poultry breeding programs.
