1 · What the graph read from it

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.

2 · The registry

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

Runs of homozygosity (ROH) are contiguous homozygous genomic segments that provide valuable insights into population history, selection pressures, and inbreeding levels. However, the global distribution of ROH and their implications for pig domestication and breeding are not yet fully understood. In this study, we analyzed whole-genome resequencing data from 1203 pigs across 49 breeds to characterize ROH patterns worldwide. European commercial pigs exhibited longer and more numerous ROH segments than Asian indigenous breeds, indicative of stronger artificial selection and higher inbreeding. Crossbreeding led to a reduction in ROH burden, with greater reductions observed when parental genetic divergence was larger. Notably, Asian and European pigs displayed distinct ROH islands, reflecting divergent selection pressures. Functional analysis revealed that these ROH islands were associated with growth, immunity, and reproduction. These findings enhance our understanding of the genetic diversity and selection history of global pig populations, providing valuable insights for future breeding strategies.
