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

Appendectomy has been associated with reduced risk of developing ulcerative colitis (UC) or experiencing flares after diagnosis, suggesting the appendix may play a role in UC pathogenesis. Given its function in microbial homeostasis and gut immunity, we investigated the relationship between mucosal microbiota and immune environment of the appendix in UC. Appendix tissue was collected from 85 patients undergoing surgery for UC, acute appendicitis (APA) or colon cancer (CC). Immunophenotyping of dendritic cells (DC), macrophages and T lymphocytes was performed using flow cytometry. Microbiota composition was analyzed via 16S rRNA gene amplicon sequencing. Although alpha diversity did not differ between UC and non-UC appendices, beta diversity indicated significant compositional differences. Five bacterial species (
