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

The Tibetan wild donkey (Equus kiang) is an endemic equid species inhabiting the Qinghai-Tibet Plateau, exhibiting remarkable chromosomal diversity within the Equus genus. Here we present a chromosome-level, telomere-to-telomere genome assembly for E. kiang generated using Illumina short reads, PacBio HiFi long reads, and Hi-C sequencing data. The final assembly spans 4.02 Gb and comprises 27 pseudochromosomes. Specifically, 8 chromosomes are gapless, 8 chromosomes have one gap, 7 chromosomes have 2-4 gaps, and the remaining 4 chromosomes have five or more gaps. Benchmarking Universal Single-Copy Orthologs (BUSCO) analysis indicated 96.7% completeness, demonstrating high assembly quality. Comparative genome collinearity with the domestic horse (E. caballus) showed that 11 E. kiang chromosomes displayed a simple one-to-one chromosome-scale correspondence. We further characterized genomic features associated with these regions, including the enrichment of tandem repeats near recombination breakpoints. This high-quality genome assembly provides a foundational resource for studies of chromosome evolution, speciation, and genomic architecture in Equus and other mammals.
