Human Fecal Transplantation Modifies the Gut Microbiota but Not Metabolites in Colon Cancer Patient-Derived Xenografts.
Article in International journal of molecular sciences, 2026. 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
Gut microbiota influences colorectal cancer (CRC) development, tumor progression, and response to therapy. Fecal microbiota transplantation (FMT) has been proposed as a strategy to restore microbial balance and modulate treatment outcomes. We evaluated the effects of human fecal transplantation on gut microbiota composition, metabolites, tumor growth, and the efficacy of folinic acid, fluorouracil and oxaliplatin (FOLFOX) chemotherapy in four CRC patient-derived xenograft (CRC PDX) models in NSG mice. Gut microbiota was profiled by 16S rRNA sequencing; short-chain fatty acids (SCFAs) and amino acids (AAs) were analyzed by mass spectrometry. Prolonged FMT significantly altered gut microbiota structure, increasing α-diversity and modifying β-diversity, and induced distinct changes in bacterial genera. FMT alone did not affect tumor growth. FOLFOX inhibited tumor progression in all CRC PDXs, with FMT enhancing therapeutic efficacy in two models. Despite substantial microbiota shifts, FMT exerted minimal or no effect on fecal SCFAs and AAs. FMT induced robust microbiota remodeling but did not modify selected stool metabolites or intrinsic tumor growth. However, FMT enhanced FOLFOX responsiveness in selected CRC PDXs, supporting a microbiota-mediated modulation of chemotherapy outcomes.
