Genome-wide genotyping uncovers genetic diversity, phylogeny, signatures of selection, and population structure of Chinese Jiangquhai pigs in a global perspective1.
Article in Journal of animal science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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.
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
Jiangquhai pigs are one of the 42 representative local breeds listed in the national livestock genetic resources conservation project of China. This breed is known for its prolificacy, desirable meat quality, and excellent adaptability to crude feed and local environments. In this study, we genotyped 105 Jiangquhai pigs from the state conservation farm using GeneSeek GGP Porcine 80K SNP chip, and explored the SNP data to unravel genetic diversity, evolutionary phylogeny, signatures of selection, and population structure of Jiangquhai pigs in a context of 33 global breeds. Five indices of observed heterozygosity, expected heterozygosity, effective population size, runs of homozygosity, and linkage disequilibrium extent indicate that the Jiangquhai breed are still rich in genetic diversity in comparison with other breeds also from East China despite the recent decline of its population size. Phylogenetic, principal component, TreeMix, and admixture analyses show that Jiangquhai pigs represent an authentic genetic resource and have close genetic relationships with East Chinese breeds, their geographical neighbors. A genome scan unravels a list of reproduction-related genes potentially under selection in Jiangquhai pigs. Using the neighbor-joining clustering approach, we reconstructed the family structure of the conservation population of Jiangquhai pigs. This finding allowed us to suggest a rotational mating scheme across the reconstructed families to reduce the risk of inbreeding depression in the population.
