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

Understanding the genetic status of captive animal populations is essential for their long-term conservation and effective management. In this study, we investigated the genetic origin, admixture patterns, and genomic health of red junglefowls (Gallus gallus; RJFs) maintained in zoological parks (zooRJFs). We conducted whole-genome sequencing of 27 zooRJFs and performed comparative population genomic analyses with wild RJFs and domesticated chicken breeds. Our analyses revealed that zooRJFs originated from Gallus gallus spadiceus. We also found that zooRJFs have undergone severe population bottlenecks, resulting in reduced genetic diversity and extremely long runs of homozygosity. These results highlight the value of genomic approaches for tracing ancestry and assessing genetic health in zoo-managed populations and provide insights into genome-informed breeding strategies for conserving captive animals.
