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

Gymnodiptychus pachycheilus, a specialized schizothoracinae fish, exhibits remarkable morphological regression, such as near-complete scale loss, making it an important model for understanding the genomic basis of adaptation and phylogeny in this lineage. Here, we assembled a high-quality chromosome-level reference genome of G. pachycheilus by Illumina short reads, PacBio HiFi long reads, and Hi-C technologies. The final genome assembly spans 1.83 Gb, with 95.52% of the sequences anchored onto 25 pseudochromosomes, a contig N50 of 71.36 Mb, and a BUSCO completeness of 98.40%. Repetitive sequences accounted for 47.75% of this genome. We predicted 48,952 protein-coding genes, of which 92.51% were functionally annotated using multiple public databases, together with diverse classes of non-coding RNAs. This genome assembly represents the first high-quality reference for G. pachycheilus and provides a valuable resource for exploring genome evolution, rediploidization processes, and adaptive mechanisms of schizothoracinae fishes on the Qinghai-Tibet Plateau.
