1 · What the graph read from it

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.

2 · The registry

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

Chemotherapy-induced diarrhea (CID) is a frequent gastrointestinal side effect in cancer patients, particularly associated with the use of 5-fluorouracil (5-FU). This study aimed to isolate multiple Bacteroides strains from the feces of healthy individuals and identify Bacteroides eggerthii (B. eggerthii) S13-F8 as the optimal candidate for alleviating CID. Whole-genome sequencing of B. eggerthii S13-F8 was conducted to uncover its functional characteristics and explore the potential mechanisms underlying its protective effects against CID. The anti-CID efficacy of B. eggerthii S13-F8 was assessed using multiple parameters, including diarrhea severity, food intake, and body weight changes. Comprehensive analyses, including blood tests, intestinal histopathology, colon transcriptomics, and fecal metagenomics, were performed to elucidate its underlying mechanisms. In a 5-FU-induced mouse model, B. eggerthii S13-F8 significantly alleviated weight loss and diarrhea. Histological examination revealed that B. eggerthii S13-F8 preserved the villus height-to-crypt depth (V/C) ratio and protected goblet cells in colonic tissues. Gene expression analysis showed that B. eggerthii S13-F8 upregulated protective markers, such as Aqp8, Slc26a3, and mucin-related genes (TFF3, FCGBP, and Muc2), while downregulating pro-inflammatory mediators, including IL-1α, IL-22, and Cxcl2. Furthermore, B. eggerthii S13-F8 modulated gut microbiota composition by suppressing pathogenic bacteria (Pseudomonas aeruginosa, Salmonella, γ-Proteobacteria, and Shigella) and enriching beneficial taxa, such as Lactobacillus and Akkermansia muciniphila. In conclusion, B. eggerthii S13-F8 demonstrates significant potential in mitigating severe diarrhea caused by 5-FU chemotherapy, providing a strong foundation for its development as a live biotherapeutic for CID treatment.
