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

Introduction: Kele pig (KLP) is a valuable Chinese indigenous pig breed, renowned for its strong adaptability, high intramuscular fat content, and excellent meat quality. However, the genomic characteristics of KLPs are still unknown. This study aims to investigate the genetic diversity, population structure, and trait-related selection signatures of KLPs based on whole-genome resequencing. Methods: The genomes of 30 KLPs were resequenced and analyzed alongside genomic data from 90 pigs of three commercial breeds, comprising 30 Duroc (DUPs), 30 Landrace (LRPs), and 30 Yorkshire pigs (YRPs). To evaluate their genetic diversity, we calculated the expected heterozygosity, observed heterozygosity, polymorphic marker ratio, minor allele frequency, nucleotide diversity (π), runs of homozygosity (ROH), and inbreeding coefficient (F Results and Discussion: A total of 66,204,339 autosomal single nucleotide polymorphisms (SNPs) were detected in the 120 pigs, and 21,738,497 SNPs were retained for further analysis after filtering. The results showed that KLPs had higher genetic diversity, along with the smallest FROH value compared to DUPs, LRPs, and YRPs. Moreover, KLPs displayed a relatively unique genetic structure with a higher LD decay, and the majority of individuals within the KLPs exhibited distant genetic distances and relationships. Totals of 688 selected regions were identified, including 723 published QTLs. Within the selected regions, 192 candidate genes were annotated, and seven genes were found to be functionally involved in coat color (
