Population structure and genetic diversity of the endangered fish black shinner Pseudopungtungia nigra (Cyprinidae) in Korea: a wild and restoration population.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
The black shinner Pseudopungtungia nigra Mori, 1935 is an endangered fish endemic to Korea. It lives in the narrow basin of the Geumgang River, Mangyeonggang River, and Ungcheoncheon Stream, which flow into the West Sea of Korea. One population of P. nigra in Ungcheoncheon Stream has been locally exterminated once; it is now inhabiting the upper reaches of the dam through a restoration program. Efforts to identify and understand the genetic structure of these populations are important for conservation planning. Here, we analyzed genetic diversity using 21 microsatellite markers for 9 populations. The mean number of alleles ranged from 4.4 to 8.1, mean allelic richness ranged from 4.6 to 7.8, mean observed heterozygosity ranged from 0.519 to 0.702, and mean expected heterozygosity ranged from 0.540 to 0.763. All groups had recent and historical bottlenecks (P < 0.05, M-ratio < 0.68). Three groups [YD (2019), OC and UC] had significant inbreeding index values, suggesting that they were engaged in inbreeding. We observed a moderate level of genetic differentiation between MG and the rest of the population (F
