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

Schizothorax davidi, a cold-water fish endemic to the Qinghai-Tibetan Plateau (QTP), represents an important economic resource in the upper Yangtze River. Regarded as a promising model for studying high-altitude adaptation and polyploidization, this species has still lacked a reference genome. Here, we report a haplotype-resolved, chromosome-scale genome of S.davidi (4n = 98), generated by integrating PacBio HiFi, Oxford Nanopore ultralong, and Hi-C sequencing data. The assembly spans 3.7 Gb across 98 chromosomes with a scaffold N50 of 36.93 Mb, includes 98,079 annotated protein-coding genes, and reveals large-scale regions of lost heterozygosity across 11 chromosomes. This haplotype-resolved genomic resource will advance the study of vertebrate polyploidy and adaptive evolution.
