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

Coilia nasus is a key migratory fish species with significant economic and ecological importance. Its sister species, Coilia brachygnathus, exhibits minimal morphological differentiation but substantial genetic divergence and a markedly lower economic value compared to C. nasus. In this study, we employed whole-genome resequencing to analyze the genetic clustering, principal components, and population structure of both C. nasus and C. brachygnathus. We report the first discovery of natural hybridization between these species in Poyang Lake. Given the difficulty in identifying hybrids based on morphology, we screened for diagnostic genetic markers and identified a short interspersed nucleotide element, T41-2. This element contains a 37-bp InDel region that differs between the C. nasus and C. brachygnathus genomes. The T41-2 InDel marker can be amplified by PCR, visualized via agarose gel electrophoresis, and has been verified as a stable and effective tool for distinguishing C. nasus, C. brachygnathus, and their interspecific hybrids across populations. This represents the first InDel marker enabling rapid discrimination between C. nasus, C. brachygnathus, and their hybrids. This marker is invaluable not only for detecting natural hybrids but also for mitigating artificial hybridization within the Chinese aquaculture industry.
