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

Despite its wide presence in cold-water bodies of central Asian mountains, Schizothorax plagiostomus is highly neglected Himalayan ichthyofauna. Here we have performed de novo RNA-sequencing in adult S. plagiostomus gonads captured from natural habitat of Garhwal Himalaya [during three distinct maturational stages (pre-spawning, spawning and post-spawning) for both sexes] and compared the season and sex specific differential transcriptomic profiles. Functional analyses of KEGG pathway and GO enrichment demonstrated augmentation in cellular signaling for multiple growth factors, chemokines, cytokines, exosomes and vascular patterning in pre-spawning gonads, rise in t-RNA biosynthesis, chaperone cofactor dependent protein refolding, steroidogenic and calcium signaling network at spawning time, whereas elevated proteolysis, autophagy and apoptotic pathways were prevalent during regressing stages. Among differentially expressed genes (DEGs) distinct sexual dimorphic pattern of male specific Dmrt1, Sox18, Amh, Wt1, GDNF receptor α and female specific Foxl2, Gdf9, Zar1,Cyp19a1a, Wntless were observed.Collectively, this is the first comprehensive gonadal atlas of season dependent developmental transcriptome with respective gametogenic output in any Schizothoracine species. This data will potentially serve as a vital resource for future programs in conservation management and artificial breeding of schizothoracine fishes.
