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

Oyster pompano (Trachinotus anak) is currently the highest-yielding marine aquaculture fish species in China. However, previously available genome assemblies were fragmented and incomplete, hindering advances in genomic research and breeding applications. Here, we generated two haplotype-resolved, telomere-to-telomere (T2T) genome assemblies for a female T. anak using PacBio HiFi, ONT ultra-long, and Hi-C data. The resulting assemblies (haplotype A and B) span 663.78 Mb and 661.09 Mb with contig N50 of 28.62 Mb and 29.02 Mb, respectively. Both haplotypic assemblies were anchored into 24 gap-free chromosomes, each comprising a complete set of 48 telomeres. The quality value (QV) scores were 70.45 and 68.66, and Benchmarking Universal Single-Copy Orthologs (BUSCO) completeness scores were 98.9% and 99.0% for haplotype A and B, respectively. Genome annotation identified 187.94 Mb and 178.63 Mb of repetitive sequences, and predicted 23,118 and 23,119 protein-coding genes in haplotypes A and B, respectively, with 99.79% and 99.78% functionally annotated. These two high-quality T2T assemblies provide invaluable resources for molecular breeding and advancing biological and evolutionary research in T. anak.
