Population genetics analysis based on mitochondrial cytochrome c oxidase subunit I (CO1) gene sequences of Cottus koreanus in South Korea.
Article in Genes & genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe freshwater sculpin Cottus koreanus is endemic to the Korean Peninsula and has a fluvial life history. However, its population has been greatly reduced and it is now listed as an endangered class II species.
objectiveTo obtain important information for its conservation, we examine the genetic diversity, population structure, and demographic history of C. koreanus through mitochondrial cytochrome c oxidase subunit I (CO1) gene sequence analysis.
methodsWe analyzed the CO1 gene sequences of 430 individuals of C. koreanus from 23 populations in South Korea.
resultsIn all, 32 haplotypes were defined by 124 variable nucleotide sites, of which 28 were unique haplotypes not shared with other regional populations. All sampled populations had high haplotype diversity (H
conclusionsC. koreanus inhabits the upper reaches of rivers and has extremely low dispersal ability, resulting in unique genetic structure patterns among populations. Therefore, all populations should be managed and conserved separately.
