Potential Modulatory Roles of Gut Microbiota and Metabolites in the Associations of Macronutrient-to-Physical Activity Ratios With Dyslipidemia.

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
backgroundLifestyle factors toward diet and physical activity (PA) may directly influence the pathophysiology of dyslipidemia. However, the associations of the specific macronutrient-to-PA ratio with dyslipidemia, and the underlying mechanisms regarding gut microbiota and metabolites, remain largely unexplored.
methodsDietary and PA information from 273 participants with or at risk of metabolic syndrome was collected via a food frequency questionnaire and the International Physical Activity Questionnaire. Gut microbial genera and fecal metabolites were profiled through 16S rRNA sequencing and untargeted LC-MS metabolomics, respectively. Machine-learning algorithms were applied to identify gut microbiome features of macronutrient-to-PA ratios and to construct microbiome risk score.
resultsHigher macronutrient-to-PA ratios, especially for high saturated fatty acid intake, were associated with increased risks of dyslipidemia, with adjusted odds ratio (95% CIs) of 2.87 (1.41-5.99) for hypercholesteremia, 2.21 (1.11-4.48) for hypertriglyceridemia, and 2.52 (1.26-5.16) for high low-density lipoprotein cholesterol. Microbiome risk scores were significantly associated with elevated levels of total cholesterol, triglycerides, and low-density lipoprotein cholesterol. Additionally, for each macronutrient-to-PA ratio, a core group of gut microbial genera were identified (eg,
conclusionsThis study identified varied associations between macronutrient-to-PA ratios and dyslipidemia and depicted the potential modulatory roles of gut microbiota and fecal metabolites.
