Mechanistic insights into fecal microbiota transplantation for the treatment of ulcerative colitis: analysis of the STOP-Colitis trial.
Trial report in Journal of Crohn's & colitis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 AND
aimsFecal microbiota transplantation (FMT) is a promising therapy for ulcerative colitis, but variable responses and unclear mechanisms limit its efficacy. We aimed to compare nasogastric versus colonic FMT delivery and define the microbial and immunological changes associated with clinical response.
methodsIn this prospective, open-label, randomized pilot trial (STOP-Colitis), 30 adults with active ulcerative colitis were randomized to receive multidose FMT via nasogastric tube or colonoscopy with subsequent enemas. Key endpoints were clinical outcomes at week 8 and longitudinal multi-omic analyses of stool and biopsies to define changes in microbial composition (16S rRNA and shotgun metagenomics), short-chain fatty acids (SCFAs), mucosal T-cells, and host gene expression.
resultsColonic FMT was superior to nasogastric delivery, with a higher clinical response rate at week 8 (75% [9/12] vs 25% [2/8]; risk ratio 2.94, 95% CI 0.84-10.30-per protocol analysis). Response was underpinned by successful microbial engraftment, leading to significantly increased fecal microbial diversity and enrichment of SCFA-producing taxa, including Oscillospiraceae and Christensenellaceae. This correlated with reduced fecal calprotectin. Responders showed a significant increase in mucosal regulatory T cells (P = .01), with a concurrent decrease in Th17 (P = 0.03) and CD8+ T cells. This anti-inflammatory shift was confirmed by mucosal transcriptomics, which revealed upregulation of metabolic pathways and downregulation of proinflammatory defense pathways in responders. (Trial registration: ISRCTN74072945).
conclusionColonic FMT is a more effective delivery route than nasogastric administration. Clinical response is driven by the engraftment of immunomodulatory bacteria that restore a healthy host-microbe dialogue, providing rationale for developing targeted microbial therapeutics.
