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

As a protandrous hermaphroditic fish species with natural sex change from male to female, Asian seabass (Lates calcarifer) represents an attractive model for studying sequential hermaphroditism. In this study, we constructed the first telomere-to-telomere (T2T) gap-free genome assembly of Asian seabass, by integration of MGI short-read, PacBio HiFi long-read, ONT ultra-long and Hi-C sequencing technologies. The haplotypic 614.19 Mb genome sequences were successfully anchored onto 24 chromosomes, demonstrating exceptional contiguity with a contig N50 of 26.57 Mb. Comprehensive annotation revealed precise localization of telomeric repeats and centromeric regions across various chromosomes. Good results from Merqury (QV: 57.8), CRAQ (99.45%) and BUSCO (100%) indicate a high level of accuracy for the assembled genome. ONT ultra-long and PacBio HiFi sequencing data were aligned with the assembly using minimap2, resulting in a mapping rate over 98%. Repetitive elements accounted for 18.18% (111.64 Mb) of the entire genome, and a total of 25,093 protein-coding genes were annotated. This high-quality T2T genome assembly provides a valuable genetic resource for in-depth comparative genomics, population genetics, molecular breeding, and functional studies of this economically important marine species. This reference assembly also facilitates investigations into the detailed molecular mechanisms underlying its unique reproductive strategy of the protandrous hermaphrodite Asian seabass.
