Effect of combined continuity care guided by Orem's self-care model and low FODMAP diet on gut microbiota composition and symptoms in patients with irritable bowel syndrome.
Article in BMC gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIrritable bowel syndrome (IBS) is a common functional gastrointestinal disorder, affecting 10%-15% of the global population, characterized by symptoms such as abdominal pain, bloating, and altered bowel habits. A low fermentable oligo-, di-, and mono-saccharides and polyols (FODMAP) diet has shown promise in managing IBS symptoms. This study evaluates the combined impact of continuity care guided by Orem's Self-Care Model with a low FODMAP diet on gut microbiota composition and IBS symptoms.
methodsA retrospective cohort study included 196 patients with IBS, divided into conventional treatment (n = 84) and low FODMAP care (n = 112) groups. The intervention spanned six weeks, integrating Orem's Model to enhance dietary adherence. Outcomes were assessed using IBS Symptom Severity Scale (IBS-SSS), gut microbiota analysis via qPCR, and quality of life measures (IBS-QOL, SF-36).
resultsBaseline characteristics between the groups showed no significant differences. Post-intervention, the low FODMAP group experienced significant improvements in IBS-SSS scores, reporting reduced abdominal pain severity (P = 0.01), frequency (P = 0.002), bloating (P = 0.006), and greater bowel movement satisfaction (P = 0.003). Gut microbiota analysis revealed increased Bifidobacterium and Lactobacillus, and decreased Enterococcus levels in the low FODMAP group (P < 0.001). SF-36 scores indicated elevated physical functioning (P < 0.001), role physical (P = 0.002), and mental health (P = 0.005) domains. Notably, IBS-QOL scores improved markedly, especially in dysphoria (P = 0.003), worry about symptoms (P = 0.001), and food avoidance (P = 0.004).
conclusionThe integration of a low FODMAP diet with continuity care guided by Orem's Self-Care Model significantly alleviates IBS symptoms and improves gut microbiota composition and quality of life.
