1 · What the graph read from it

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.

2 · The registry

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

purposeObesity and its associated comorbidities, including chronic inflammation, pose significant public health challenges. Recent studies have suggested a link between obesity and gut microbial dysbiosis, with exercise emerging as a potential modulator of gut microbiota by enhancing microbial diversity and short-chain fatty acid (SCFA) production. However, the effects of exercise on the microbiome diversity and composition in overweight individuals or with obesity remain inconsistent.

methodsThis study systematically reviewed literature from PubMed, Embase, Cochrane Library, and ScienceDirect databases up to November 5, 2024, following PRISMA guidelines. Eleven studies were included in the systematic review, and four studies with quantitative data were analyzed using meta-analysis (Comprehensive Meta-Analysis software) and the ROB tool.

resultsThe meta-analysis showed a statistically significant effect of exercise on beta diversity. The pooled effect size for Bray-Curtis dissimilarity was 4.56 (95% confidence interval (CI) [1.77, 11.80], Z = 3.14, P = 0.002). These findings suggest that exercise positively influences gut microbial structure in overweight individuals or with obesity.

conclusionExercise may be a key component of lifestyle modification to modulate the gut microbiota and improve metabolic health in overweight individuals or with obesity. Future studies should evaluate the independent effects of fitness improvement and weight loss on gut microbial composition by employing multi-omics and metabolic pathway analyses to develop personalized obesity management strategies.
