Single nucleotide polymorphism-based analysis of the genetic structure of the Min pig conserved population.
Article in Animal bioscience, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
objectiveThe study aims to uncover the genetic diversity and unique genetic structure of the Min pig conserved population, divide the nucleus conservation population, and construct the molecular pedigree.
methodsWe used KPS Porcine Breeding Chip v1 50K for SNP detection of 94 samples (31♂, 63♀) in the Min pig conserved population from Lanxi breeding Farm.
resultsThe polymorphic marker ratio (PN), the observed heterozygosity (Ho), and the expected heterozygosity (He) were 0.663, 0.335, and 0.330, respectively. The pedigree-based inbreeding coefficients (FPED) was significantly different from those estimated from runs of homozygosity (FROH) and single nucleotide polymorphism (FSNP) based on genome. The Pearson correlation coefficient between FROH and FSNP was significant (p<0.05). The effective population content (Ne) showed a continuously decreasing trend. The rate of decline was the slowest from 200 to 50 generations ago (r = 0.95), then accelerated slightly from 50 to 5 generations ago (1.40<r<1.50) and increased significantly in the last 5 generations (r = 2.6). According to the composition of Chinese lineage, we separated the nucleus conservation population (81 individuals) and the candidate conservation population (13 individuals) of Min pig, then the nucleus conservation population of Min pig was divided into 9 families by genomic information matrix.
conclusionOur study indicated that the genetic diversity of the Min pig conserved population was inadequate. Due to the introgression of European commercial pig breeds and the unscientific breeding process, it is necessary to construct the molecular pedigree of the nucleus conservation population for the Min pig.
