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
backgroundThe human microbiome plays a vital role in human health, mediated by the gut-brain axis, with a large diversity of functions and physiological benefits. The dynamics and mechanisms of meditations on oral and gut microbiome modulations are not well understood. This study investigates the short-term modulations of the gut and oral microbiome during an Arhatic Yoga meditation retreat as well as on the role of microbiome in improving well-being through a possible gut-brain axis.
methodsA single-arm pilot clinical trial was conducted in a controlled environment during a 9-day intensive retreat of Arhatic Yoga meditation practices with vegetarian diet. Oral and fecal samples of 24 practitioners were collected at the start (Day0: T1), middle (Day3: T2), and end (Day9:T3) of the retreat. Targeted 16S rRNA gene amplicon sequencing was performed for both oral and gut samples. Functional pathway predictions was identified using phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt2). DESeq2 was used to identify the differential abundant taxa. Various statistical analyses were performed to assess the significant changes in the data.
resultsOur findings revealed that Arhatic Yoga meditation together with a vegetarian diet led to changes in the oral and gut microbiome profiles within the 9-day retreat. Oral microbiome profile showed a significant (p < 0.05) difference in the species richness and evenness at the end of study, while non-metric multidimensional scaling (NMDS) confirmed the shift in the gut microbiome profile of the practitioners by T2 timepoint, which was further supported by PERMANOVA analysis (p < 0.05). Health-benefiting microbes known to improve the gastrointestinal and gut-barrier functions, immune modulation, and gut-brain axis were enriched. Gut microbiome of both beginner and advanced Arhatic Yoga practitioners showed similar trends of convergence by the end of study. This implies a strong selection pressure by Arhatic Yoga meditation together with a vegetarian diet on the beneficial gut microbiome.
conclusionThis pilot study demonstrates that Arhatic Yoga meditation practices combined with a vegetarian diet during a short intensive retreat resulted in enrichment of known health-promoting microbes. Such microbial consortia may be developed for potential health benefits and used as probiotics to improve the gastrointestinal and immune systems, as well as functions mediated by the gut-brain axis.
