A chromosome-level genome assembly of the male darkbarbel catfish (Pelteobagrus vachelli) using PacBio HiFi and Hi-C data.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
The darkbarbel catfish (Pelteobagrus vachelli), a species of significant economic value in China's aquaculture sector, is widely utilized in hybrid yellow catfish production due to its exceptional growth rate. The growth rate of male P. vachelli is significantly higher compared to females, making all-male breeding a promising market opportunity. Therefore, the analysis of the male P. vachelli genome provides crucial genetic information for hybrid breeding and all-male breeding. Utilizing PacBio Hifi long-read sequencing and Hi-C technologies, we present a high-quality, chromosome-level genome assembly for the male P. vachelli. The assembly covers 728.88 Mb with 99.92% of the sequence distributed across 26 chromosomes. The contig N50 is 5.60 Mb, and the scaffold N50 is 28.76 Mb. The completeness of the P. vachelli genome assembly is highlighted by a BUSCO score of 97.45%. The genome is estimated to encode 25,121 protein-coding genes, with 93.46% annotated functionally and a BUSCO score of 96.40%. Repeat elements constitute approximately 38.97% of the genome. This comprehensive genome assembly represents an invaluable resource for advancing hybrid breeding, comparative genomics, and evolutionary studies in catfish and related species.
