Interventions Targeting the Gut Microbiome to Improve Cancer Treatment Outcomes and Their Gastrointestinal Side Effects: A Systematic Review and Meta-analysis.

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
backgroundImprovements in cancer treatment are essential to reduce premature mortality. Emerging evidence highlights the role of the gut microbiome (GM) in influencing treatment responses and modulating gastrointestinal adverse events (GIAEs). Because cancer therapy disrupts GM composition, restoring gut health may help mitigate side effects and support gut-associated immunity.
objectivesThis study aimed to systematically evaluate and assess the effectiveness of GM interventions on the occurrence of GIAEs and clinical responses to cancer treatment.
methodsThree databases (PubMed, Web of Science, and Cochrane Library) were systematically searched up to February 2025 for studies assessing GM interventions during cancer treatment. Risk of bias was evaluated using the Effective Public Healthcare Panacea Project Quality Assessment tool. Meta-analyses were conducted in Stata 18 using random-effects models to estimate the pooled relative risk of GM interventions on gut microbiome interventions, gastrointestinal adverse events (GIAEs) (primary outcome) and objective disease response rates (secondary outcome).
resultsFifty-six studies were included in the systematic review, and 40 were meta-analyzed (n = 37 for GIAE outcomes, n = 8 for treatment response). GM interventions reduced the overall risk of GIAEs [relative risk (RR)]: 0.59; 95% CI: 0.53, 0.65; I
conclusionsGM interventions show promise in improving cancer care by reducing GIAEs, although evidence for direct effects on-treatment response remains limited. Standardizing intervention protocols and outcome reporting in future RCTs is essential to strengthen the evidence base and guide clinical recommendations. This trial was registered at PROSPERO as CRD42023443332 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023443332).
