Gut microbiome signatures in colorectal neoplasia: a cross-sectional study across neoplasia stages and subtypes.
Observational study in Gut, 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
backgroundWhile colorectal cancer (CRC) has been linked to the gut microbiome, it remains unclear whether specific microbial signatures are detectable in precursor lesions such as adenomatous polyps, serrated lesions or sessile serrated lesions.
objectiveTo assess gut microbiome taxonomic and functional associations with colorectal neoplasia presence, severity (non-advanced, advanced and CRC) and subtype and evaluate predictive potential in high-risk neoplasia.
designAnalysed cross-sectional stool metagenomes (pre-colonoscopy) from 1762 participants (97% White British) undergoing colonoscopy in the multicentre COLO-COHORT study. Neoplasia was classified per British Society of Gastroenterology surveillance guidelines. Linear mixed-effects models and random forest classifiers assessed taxonomic and functional associations, adjusting for dietary, clinical and lifestyle covariates.
resultsGut microbiome composition differences between individuals with and without neoplasia were statistically significant but minimal (R
conclusionThis large prospective cross-sectional study found weak and inconsistent associations between the gut microbiome and premalignant colorectal neoplasia, with no robust microbial signatures. Findings suggest that previously reported microbial shifts may emerge later in disease progression, potentially as a consequence rather than a cause of CRC. Longitudinal, multiomic studies disentangling temporal and causal pathways between the gut microbiome and neoplasia are required.
