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

Local chicken breeds have long been subjected to unique geographical isolation and extreme environmental pressures, which have led to significant environmental adaptation. This provides a valuable opportunity to explore the mechanisms of adaptive evolution in domestic chickens and to develop rare genetic resources. However, the molecular genetic basis of these local breeds remains inadequately studied. In this research, we systematically compared the population genetic structure and selection signals between the Hotan Black Chicken (HT) from Xinjiang and the F2 hybrid population of Yeonsan Ogye × White Leghorn chickens (OLF) based on medium-density SNP chip data. Principal Component Analysis (PCA), Neighbor-Joining (NJ) phylogenetic trees, and ancestry inference methods revealed significant genetic differentiation between the two populations. HT exhibited a relatively homogeneous genetic background, while the F2 population showed a more complex genomic structure. By combining a sliding window approach with population differentiation index (
