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

Spinibarbus hollandi is an economically significant subtropical fish in China, valued for both ornamental and aquaculture purposes. However, the full-length transcriptomic resources for this species remain scarce. To address this gap, we constructed the first multi-tissue, full-length transcriptome of S. hollandi using PacBio single-molecule real-time sequencing. We assembled 23,403 non-redundant transcripts, including 15,197 unigenes, with a mean length of 2,147 bp and an N50 of 2,868 bp. Among these, 14,567 unigenes (95.85%) were annotated in public databases. Our analysis identified 373 alternative splicing events, with retained intron being the most common type. We also predicted 2,397 long non-coding RNAs. Furthermore, a comprehensive screening revealed 7,449 simple sequence repeat (SSR) loci, comprising 1,198 compound and 6,251 perfect SSRs, with an occurrence frequency of 30.96%. Di- and tri-nucleotide repeats were the predominant types. Thirteen highly polymorphic SSR loci showed robust polymorphism across four geographical populations. This study provides a crucial data foundation and genetic resource for functional gene research, molecular marker-assisted breeding, and germplasm conservation in S. hollandi.
