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

Hilsa (Tenualosa ilisha) is crucial to Bangladesh's economy and ecology, but recent trends show early maturation in small-sized hilsa, with unclear causes. This study aimed to identify differentially expressed genes (DEGs) between the ovaries of large and small hilsa using RNA-sequencing. Samples from both sizes were collected from the Meghna River in Chandpur District, and four ovary libraries were sequenced via the Illumina platform. A total of 908 DEGs were detected, of which 453 were up-regulated and 455 were down-regulated. Transcriptome analysis revealed significant differences in Gene Ontology terms such as extracellular region (GO:0005576), innate immune response (GO:0045087), and protein ubiquitination (GO:0016567), peptide antigen binding (GO:0042605), KEGG pathways including MAPK signaling pathway (ko04010), endocytosis (ko04144), and spliceosome (ko03040), as well as COG terms like signal transduction, between the ovary of large and small hilsa shad. These findings suggest that differentially expressed genes may play a role in regulating the ovarian development of T. ilisha. However, the entire process, from sampling to final annotation, is described here, along with the workflow. This study will offer a valuable resource for current and upcoming Hilsa transcriptome-based expression profiling studies.
