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
Seasonal fluctuations in diet and climate shape animal gut microbiota, especially those living in extreme climatic conditions. Yet their role in facilitating primate adaptation to high-altitude remains unclear. This study investigates the seasonal dynamics in gut microbiome of wild rhesus macaques (Macaca mulatta) from high altitude (over 3,000 m) in Yajiang couke. We collected 117 fecal samples across four seasons and analyzed using 16S rRNA high-throughput sequencing combined with predictive functional metagenomics. We observed clear seasonal shifts in gut microbial diversity and composition. High α-diversity in autumn and winter reflected increased dietary diversity during these periods. Firmicutes predominated in summer, while Bacteroidota increased during winter. LEfSe analysis revealed seasonal specific taxa: UCG-005, Christensenellaceae R-7, and Prevotella_9 were dominated in winter but declined in summer and spring, whereas Blautia peaked during summer and decreased toward winter. Redundancy analysis showed that temperature, humidity, and precipitation were positively associated with Blautia and Sarcina, but negatively with Monoglobus and Helicobacter, underscoring the strong influence of climatic variables on gut community structure. Functional predictions revealed seasonal differences in gut microbiota related to energy metabolism (spring), glycan biosynthesis (summer), membrane transport (autumn), and environmental adaptation (winter) indicating microbial contributions to host adaptation under fluctuating climatic conditions. These findings demonstrate that gut microbiome of high-altitude macaques is highly responsive to changes in seasonal diet and climate. By integrating microbiome dynamics with climatic drivers, our study provides new insights into host-microbe-environment interactions and advances our understanding of primate adaptation under extreme climatic conditions.
