Epidemiological study on the effects of gut microbiota and nutrients on breath hydrogen and methane concentrations.

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
Breath hydrogen concentration measurement is a valuable tool for assessing the intestinal environment; however, few epidemiological studies have investigated the relationship between exhaled hydrogen and gut microbiota in healthy subjects. This study aimed to epidemiologically elucidate the relationships between exhaled hydrogen, gut microbiota, and nutrient intake in healthy residents of the Iwaki area of Hirosaki City, Aomori Prefecture, including those who exhaled methane. We categorized participants into low- and high-exhaled hydrogen groups based on the median exhaled hydrogen concentration of 6.13 ppm and matched background factors by propensity score matching for age, body mass index, and defecation habits. In the high exhaled hydrogen group, intestinal butyrate-producing bacteria such as
