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

Hetian black chicken is an indigenous breed endemic to Xinjiang, China, known for its remarkable adaptability to harsh desert environments. Age at first egg (AFE) and egg number at 300 days of age (EN300) are important reproductive traits, yet their molecular genetic basis remains unclear. Here, we combined whole-genome resequencing (64 hens) and transcriptome sequencing (ovary and uterus from 13 hens) to identify candidate genes and SNPs associated with AFE and EN300. Using F
