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

Transit time, fluid intake, diet, and overall gut health all influence stool consistency. However, the relationships between the gut microbiota, metabolome (microbial metabolites), and stool consistency in infants and young children remain poorly understood. In this study, we analyzed the microbiota and metabolome of 618 stool samples from children aged 2.5 months (n = 360), 6 months (n = 229), 14 months (n = 274), and 30 months (n = 169) from the FinnBrain Birth Cohort Study, correlating these data with stool water content and parent-reported stool consistency. We found that breastfeeding had the strongest association with both stool consistency and fecal water content. We observed that the concentrations of newly discovered microbial bile acid amidates were associated with constipation and negatively correlated with stool water content. Partial versus exclusive breastfeeding was further linked to higher levels of specific bile acid amidates through mediation by constipation. Bile salt hydrolase, an enzyme involved in deconjugating primary bile acids and generating novel microbial bile acids, was also predicted to be negatively associated with stool water content. In addition, short-chain fatty acids (SCFAs), particularly acetic acids, were positively associated with stool water content, whereas branched SCFAs showed a negative association. These findings suggest longer transit time appeared to allow more extensive bacterial metabolism of microbial metabolites, including the transformation of bile acid amidates. Here, we also observed that the relative abundances of specific genera such as
