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

The school shark, Galeorhinus galeus (Linnaeus, 1758), is the only extant species within its genus and is widely distributed in benthopelagic habitats of temperate coastal regions. Fishing pressure has caused global population declines by more than 80%, resulting in the species being listed as Critically Endangered. Here, we present the first chromosome-level, haplotype-phased reference genome assemblies for G. galeus, including assemblies of both male and female individuals. The 4.81 Gbp male genome was assembled from PacBio HiFi and Dovetail Omni-C proximity ligation sequencing data, and the 4.52 Gbp female genome was assembled from PacBio HiFi data scaffolded via homology to the curated male genome. Both genomes are >92% BUSCO complete and contain ~60-63% repeat content. Analysis of methylation levels and single nucleotide polymorphism density across chromosomes revealed several regions where high SNP density co-located with relative hypomethylation, indicating a reciprocal relationship between these two features. These genomes are a valuable resource enabling future genomic studies to inform population management and conservation strategies for this Critically Endangered species.
