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

backgroundObesity and the metabolic syndrome (MetS) are global health challenges. The gut microbiome, particularly its fermentation products, short-chain fatty acids (SCFAs), is increasingly recognized as a key modulator of cardiometabolic health. Growing evidence suggests that exercise may play a critical role in SCFA production. This study presents a pooled analysis of data from three randomized controlled trials to examine the effects of low-volume high-intensity (HIGH-EX) versus moderate-intensity (MOD-EX) interval training, each combined with single-set resistance training, on SCFAs and cardiometabolic health in obese MetS patients.

methodsData from 113 patients allocated to 12 weeks of HIGH-EX, MOD-EX, or a control group (CON) were analyzed. Fecal SCFA concentrations, cardiorespiratory fitness (VO

resultsHIGH-EX and MOD-EX improved VO

conclusionsLow-volume combined interval and resistance training improved fitness and metabolic health at both moderate and higher intensities. However, only HIGH-EX enhanced SCFA production, potentially associated with lactate-mediated microbial adaptations. Exercise intensity may thus be a key determinant of gut-metabolic benefits.
