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
backgroundAdenomatous polyposis syndromes (APS) patients with ileal pouch anal anastomosis (IPAA) suffer frequent symptoms with scarce signs of inflammation, distinct from ulcerative colitis patients. While the management of pouchitis in ulcerative colitis patients is well established, data regarding response to treatment modalities targeting pouch-related disorders in APS patient population is scarce.
aimTo assess clinical, endoscopic and histologic response to various treatment modalities employed in the therapy of pouch related disorders.
methodsAPS patients who underwent IPAA between 1987-2019 were followed every 6-12 mo and pouch-related symptoms were recorded at every visit. Lower endoscopy was performed annually, recording features of the pouch, cuff and terminal ileum. A dedicated gastrointestinal pathologist reviewed biopsies for signs and severity of inflammation. At current study, files were retrospectively reviewed for initiation and response to various treatment modalities between 2015-2019. Therapies included dietary modifications, probiotics, loperamide, antibiotics, bismuth subsalicylate, mebeverine hydrochloride, 5-aminosalicylic acid compounds and topical rectal steroids. Symptoms and endoscopic and histologic signs of inflammation before and after treatment were assessed. Pouchitis disease activity index (PDAI) and its subscores was calculated. Change of variables before and after therapy was assessed using Wilcoxon signed rank test for continuous variables and using McNemar's test for categorical variables.
resultsThirty-three APS patients after IPAA were identified. Before treatment, 16 patients (48.4%) suffered from abdominal pain and 3 (9.1%) from bloody stools. Mean number of daily bowel movement was 10.3. Only 4 patients (12.1%) had a PDAI ≥ 7. Mean baseline PDAI was 2.5 ± 2.3. Overall, intervention was associated with symptomatic relief, mainly decreasing abdominal pain (from 48.4% to 27.2% of patients,
conclusionAPS patients benefit from dietary modifications and probiotics that improve their pouch-related symptoms but respond minimally to anti-inflammatory and antibiotic treatments. These results suggest a functional rather than inflammatory disorder.
