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: Geographic variations in climate and lifestyle may be associated with hypertension (HTN) through alterations in the gut microbiota and its metabolites. This study aimed to comparatively analyze the gut microbiome and fecal metabolome of hypertensive patients from two Chinese cities characterized by distinct climatic conditions: Daqing (middle-temperate climate) and Haikou (tropical climate). The objective was to identify gut microbial and metabolic characteristics associated with geographic differences and to provide insights into HTN prevention and management. Methods: A cross-sectional study was conducted between May and December 2024, involving hypertensive patients from Daqing and Haikou. Fecal samples were collected from 28 hypertensive patients in Daqing (DQ group) and 32 in Haikou (HK group), and analyzed using shotgun metagenomic sequencing and untargeted metabolomics. Results: Differences in microbial composition and metabolite profiles were observed between the two groups. Using ALDEx2 analysis at the genus level, 34 genera were identified as differentially abundant between the DQ and HK groups. After adjusting for potential confounding variables, including age, body mass index, smoking, and drinking status, 6 genera remained significantly associated with geographic grouping. A logistic regression model based on these genera achieved an area under the curve (AUC) of 0.8069, with Conclusion: Distinct gut microbiome and metabolome profiles were observed between hypertensive patients from the two geographic regions. These findings suggest potential associations between environmental factors and host-microbiome-metabolite interactions.
