A Comparative Analysis of Clinical Symptoms and Modified Pouchitis Disease Activity Index Among Endoscopic Phenotypes of the J Pouch in Patients With Inflammatory Bowel Disease.
Article in Crohn's & colitis 360, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Background: The modified pouchitis disease activity index (mPDAI) based on clinical symptoms and endoscopic findings is used to diagnose pouchitis, but validated instruments to monitor pouchitis are still lacking. We recently established an endoscopic classification that described 7 endoscopic phenotypes with different outcomes. We assessed symptoms and compared mPDAIs among phenotypes in inflammatory bowel disease (IBD). Methods: We retrospectively reviewed pouchoscopies and classified them into 7 main phenotypes: normal ( Results: One hundred and three IBD patients were included. The median mPDAI was 0 (IQR 0-1.0) in patients with a normal pouch. Among inflammatory phenotypes, the highest median mPDAI was 4.0 (IQR 2.25-4.75) in cuffitis, followed by 3.0 (IQR 2.5-4.0) in diffuse inflammation, 2.5 (IQR 1.25-4.0) in inlet involvement, 2.5 (IQR 2.0-3.5) in AL involvement, 2.0 (IQR 1.0-3.0) in focal inflammation, and 1.0 (IQR 0.25-2.0) in the fistula phenotype. Perianal symptoms were frequently observed in pouch-related fistulas (8/10, 80%) and cuffitis (13/15, 87%). Among patients with cuffitis, all had incomplete emptying (6/6, 100%). Conclusions: We correlated the mPDAI with the endoscopic phenotypes and described the limited utility of symptoms in distinguishing between inflammatory phenotypes. Further studies are warranted to understand which symptoms should be monitored for each phenotype and whether mPDAI can be minimized after pouch normalization.
