Faecalibacterium Diversity in the Gut Microbiome of Crohn's Disease Patients.
Article in United European gastroenterology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Faecalibacterium has recently garnered attention for its potential health implications. To better understand its role, we developed and assessed real-time PCR assays for detecting and quantifying various Faecalibacterium species in human stool samples from both healthy individuals and Crohn's disease patients, either in flare or remission. The assays targeted the Microbial Anti-inflammatory Molecule (MAM) genes, which encode MAM proteins. These assays demonstrated 100% species-specificity using strains from six Faecalibacterium species: Faecalibacterium prausnitzii, Faecalibacterium taiwanense, Faecalibacterium duncaniae, Faecalibacterium longum, Faecalibacterium hattori, and Faecalibacterium CNCM4541. They also showed high sensitivity with detection limits of 10^5 bacteria per gram of sample. In healthy individuals, the different Faecalibacterium species varied in abundance. F. taiwanense, F. duncaniae, and F. longum were the most prevalent, around 10^10 bacteria/g of stool. In contrast, F. hattori and CNCM4541 were less abundant, with 10^7 bacteria/g. Despite its low abundance, F. hattori was present in all healthy subjects, while CNCM4541 was detected in only 50% of them. Notably, F. taiwanense, F. duncaniae, and F. longum were found in all healthy individuals. In Crohn's disease patients, both in flare and remission, a decrease in Faecalibacterium species was observed, with no recovery in remission. The most abundant species in Crohn's disease patients were F. prausnitzii and F. duncaniae, around 10^7 bacteria/g, while F. longum, F. hattori, and F. taiwanense were present at lower levels (10^6 bacteria/g), and CNCM4541 was no longer detected. Interestingly, F. prausnitzii showed a smaller decrease in abundance compared with other species. Moreover, F. prausnitzii was significantly more prevalent in patients in remission than in those in flare, suggesting that it may be more resistant to inflammation. These findings highlight the importance of accurately characterizing and quantifying Faecalibacterium species to better understand their role in health and disease.
