The effects of filtration and centrifugation on the gut microbiota in fecal microbiota transplantation preparation.

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
Background: The preparation method of fecal microbiota suspensions is crucial for reliable fecal microbiota transplantation research. However, current protocols vary significantly in processing parameters, potentially compromising the comparability of studies. Systematic comparisons of how different preparation techniques affect the microbial community are still lacking. Methods: Fresh fecal samples from nine adult volunteers were processed via filtration and centrifugation at various speeds. Microbial viability was assessed via live/dead staining and colony forming unit enumeration. 16S rDNA sequencing was performed to analyze bacterial diversity and taxonomic composition. Results: The microbial composition and functional potential did not differ between the filtration alone group and the fresh fecal group, and filtration resulted in the lowest bacterial mortality. Mortality increased with increasing centrifugation speed. Centrifugation selectively affected the abundance of some genera (e.g., Conclusion: Filtration alone best preserved fecal microbial viability, composition and functional potential. Centrifugation enrichment becomes selective at high speeds. Differential centrifugation offered superior impurity removal. The preparation strategy should be tailored to the research or therapeutic goal.
