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

Background/Aims: : The low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet is a well-researched treatment for diarrhea-predominant irritable bowel syndrome (IBS-D), but its value for constipation-predominant IBS (IBS-C) is uncertain. Clinicians may hesitate to recommend it for IBS-C, fearing it could worsen constipation or offer little relief. This study aims to assess the diet's effectiveness across all IBS subtypes, specifically investigating its impact on stool patterns in IBS-C and the correlation with symptom relief. Methods: : This prospective service evaluation involved 294 IBS patients (84% female, mean age 44.6) attending dietitian-led group sessions on FODMAP restriction (baseline) and reintroduction (follow-up). The primary outcome was "satisfactory relief of gut symptoms" via the global symptom question; secondary outcomes included changes in stool consistency, IBS subtype, and gastrointestinal symptoms. Results: : At baseline, 23.8% (70/294) had IBS-C and 35.7% IBS-D (105/294). All subtypes except IBS-M showed significant symptom relief at follow-up ( Conclusions: : IBS-C and IBS-D showed similar symptom relief after FODMAP restriction. Notably, 44.9% of IBS-C patients shifted to normal stool consistency (IBS-U), with greater symptom relief and reduced pain. FODMAP restriction does not necessarily exacerbate constipation in IBS-C and remains a viable treatment option in real world clinical practice.
