Telomere-to-telomere gap-free genome assembly of the Opsariichthys evolans (Cypriniformes: Cyprinidae).
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Opsariichthys evolans is a stream-dwelling fish species endemic to China, with its primary distribution encompassing southeastern China and Taiwan. Initially classified under the genus Zacco, it was later reclassified into the genus Opsariichthys based primarily on mitochondrial DNA evidence. However, this taxonomic revision remains partially inconclusive due to the absence of whole-genome data. Therefore, we assembled a telomere-to-telomere, gap-free genome assembly of O. evolans, consisting of 39 chromosomes with one contiguous sequence per chromosome. The assembly had a total size of 886.9 Mb and a contig N50 of 25.44 Mb. The presence of the telomere repeat was clearly confirmed in the genome. BUSCO assessment confirmed 99.34% genome completeness. Collinearity analysis revealed high synteny between O. evolans, O. bidens and Zacco platypus. Genomic comparisons revealed key candidate genes and related biological pathways potentially responsible for color patterning and hydrodynamic adaptation. The complete O. evolans genome provides insights into its genome structure and function, and supports the taxonomic reclassification between the genera Opsariichthys and Zacco.
