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

purposeThe anatomical location of inflammation in and around the ileal pouch affects the pouch survival rate, and diffuse inflammation has poor pouch survival rates. We aimed to clarify the symptoms and histological findings of diffuse inflammation of the pouch.

methodsWe evaluated the symptoms, treatment, and histological findings according to the endoscopic phenotypes of diffuse inflammation, focal inflammation, and normal as the pouch body phenotype and afferent limb involvement, inlet involvement, cuffitis, and fistula as the peripheral findings.

resultsOf the 318 pouchoscopies, 47 had diffuse inflammation, 201 had focal inflammation, and 70 were normal. Symptomatic patients had diffuse inflammation more frequently (46.8%) than focal inflammation (13.4%) and normal (14.2%), with no difference between focal inflammation and normal. Antibiotics and steroids were higher rate administered in cases of diffuse inflammation, but not in cases of focal inflammation or in normal cases. Histological inflammation, inflammatory bowel disease (IBD)-specific finding, and colonic metaplasia showed severity in the order of diffuse inflammation > focal inflammation > normal. The number of peripheral inflammatory findings overlapped in the following order: diffuse inflammation > focal inflammation > normal. The number of symptomatic patients increased as the number of peripheral inflammatory findings increased.

conclusionPouches with diffuse inflammation are more symptomatic, have a higher use of therapeutic agents, and have more severe histological inflammation, IBD-specific finding, and colonic metaplasia accompanying peripheral inflammatory findings than the other groups. The higher the overlap of inflammatory findings in the surrounding tissues, the more symptomatic the patients will appear.
