Short-chain fatty acids mediate interactions between immune responses and commensal bacteria in high altitude yaks.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The complex interplay between host and commensal gut microbiota affects the major biological functions such as metabolism and stress adaptation, and displays pronounced seasonality in mammals. However, the seasonal dynamic patterns of immune responses and microbiota, and their interactions remain uncertain in animals inhabiting extreme environments. We analyzed monthly hormones, immunoglobulins and fecal microbiota from yaks grazing on the Tibetan plateau. Clear seasonal patterns were observed: glucocorticoid levels peaked in the cold season, while concentrations of IgA, IgG, IgM, and short-chain fatty acids (SCFAs) increased during the warm season. Yak fecal microbiota also fluctuated seasonally, with lowest diversity in the warm season but accompanied by an enrichment of Firmicutes and Actinobacteria. Taxa such as Alistipes, Bacteroides, Romboutsia and Arthrobacter contributed to seasonal shifts in the levels of SCFAs and immunoglobulins. These results indicate that yaks synchronize peak immune activation and energy production with the nutrient-rich warm season, suggesting a role for microbiome plasticity in driving immune flexibility for high-altitude animals.
