Genetic diversity analysis of four Parabramis pekinensis populations based on microsatellite markers.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To investigate the germplasm differences between northern and southern populations of Parabramis pekinensis and analyze their genetic diversity and population structure, this study employed 10 developed microsatellite markers to analyze 133 individuals collected from the Yangtze River Basin (Jiangsu JS, Hunan HN) and the Amur River Basin (Jilin JL, Heilongjiang HLJ). The HLJ population is considered a wild stock, while the other three groups are classified as cultured populations. The analysis revealed that four Parabramis pekinensis populations exhibited high levels of genetic diversity, with polymorphic information content (PIC) ranging from 0.5130 to 0.6142. A total of 249 alleles were detected, among which the HN population showed the highest genetic diversity (Na = 8.0 ± 4.59). The analysis of molecular variance (AMOVA) revealed significant genetic differentiation among populations, with 34% of gene variation attributed to inter-population differences (Fst = 0.337). The UPGMA clustering and STRUCTURE analysis (optimal K = 3) grouped the JL and HLJ populations into a single cluster, which subsequently merged with the JS population to form a larger clade. In contrast, the HN population was distinctly separated as an independent branch. The study demonstrates that the HN population of P. pekinensis should be prioritized for conservation as a distinct genetic unit, with the enhancement of habitat connectivity among northern populations could effectively mitigate genetic diversity loss. These findings provide a scientific foundation for the preservation of P. pekinensis germplasm resources.
