Runs of Homozygosity Islands in Autochthonous Spanish Cattle Breeds.
Article in Genes, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND/
objectivesUnderstanding the genetic architecture of autochthonous European cattle breeds is important for developing effective conservation strategies and sustainable breeding programs. Spanish beef cattle, which trace their origins to ancient migrations from the Near East with later admixture from African populations, exhibit a rich genetic diversity shaped by environmental adaptation and selective breeding. Runs of Homozygosity (ROH) are extended stretches of identical genetic material inherited from both parents. They serve as indicators of inbreeding and selection signatures within populations. ROH islands, or regions of the genome where ROH segments are highly concentrated across individuals within a breed, indicate genomic regions under selective pressure.
methodsThis study explores the distribution of ROH islands across seven Spanish beef cattle breeds (Asturiana de los Valles, Avileña-Negra Ibérica, Bruna dels Pirineus, Morucha, Retinta, Pirenaica, and Rubia Gallega). By analyzing high-density SNP data, we characterized ROH patterns and identified genomic regions with high levels of homozygosity, which may indicate selection pressures or common ancestry.
resultsOur findings revealed breed-specific ROH patterns as well as shared ROH islands, underscoring genetic relationships and differentiation among the breeds. Notably, Morucha displayed the highest number of ROH, while Asturiana de los Valles had the fewest. F
conclusionsThis study offers valuable insights for breeding strategies and conservation efforts, highlighting the genetic diversity and historical background of Spanish cattle breeds.
