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

backgroundLarimichthys crocea, commonly known as large yellow croaker, is a marine species of significant commercial value in East Asia. However, overfishing and long-term artificial breeding have raised concerns about the genetic diversity and adaptive capacity of farmed populations. Understanding the genetic differentiation and environmental adaptation between wild and cultured populations is crucial for conservation efforts and sustainable aquaculture development.

resultsWhole-genome resequencing of 195 individuals revealed: (1) Significant genetic divergence between wild and farmed populations (764,656 SNPs), with cultured stocks showing 18-22% lower heterozygosity; (2) 153 selective sweep regions containing 739 candidate genes, including hsp40 (thermal adaptation) and ndufs6 (energy metabolism); (3) Genome-environment association identifying 9,265 loci linked to salinity, temperature, and dissolved oxygen (RDA adj. R²=0.036, P < 0.001); (4) Strong isolation-by-environment patterns (Mantel R²=0.89, P = 0.042) outweighing geographical distance effects.

conclusionsOur results demonstrate that environmental factors rather than geography drive genetic differentiation in L. crocea, with aquaculture populations exhibiting signatures of both artificial selection and reduced adaptive potential. These findings provide actionable insights for conservation management and marker-assisted breeding to maintain genetic diversity in cultured stocks.
