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

Clostridioides difficile exemplifies a pathogen that leverages its metabolic plasticity to exploit nutrients that become available during community disruption, including host and microbiota-derived metabolites and substrates enriched in modern diets. These ecological dynamics underpin the high and growing burden of C. difficile infection (CDI), including recurrent disease and the rising prevalence of community-associated CDI. Fecal microbiota transplantation and standardized stool-derived products consistently re-establish colonization resistance through convergent functions that include secondary bile acid restoration, nutrient niche exclusion, and suppression of opportunistic pathogens. These principles have provided a valuable roadmap for rational consortia design. In this review, we synthesize current ecological mechanisms governing C. difficile colonization, persistence, and recurrence, highlight missing dimensions in diet intervention studies and mucosal colonization by C. difficile, and propose an ecology-informed, artificial intelligence-enabled precision framework that integrates host susceptibility, exposures, diet, community function, and pathogen features to guide personalized prevention and treatment.
