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

Indigenous chickens are an important genetic resource in Botswana, providing protein, cultural value and economic benefits to rural communities. The Tswana chicken, comprising multiple strains including Dwarf, Nakedneck, and Normal, has been shaped by domestication, local adaptation and traditional management practices. However, the lack of structured breeding strategies raises concerns about genetic erosion. This study evaluated genomic inbreeding patterns and signatures of selection in Tswana chicken strains using genome-wide SNP data from the 60 K iSelect chicken array. After quality control in PLINK v1.9, 52,719 SNPs from 81 chickens were retained for analysis. Runs of homozygosity (ROH) analysis and complementary selection signature approaches (F
