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

Background: In this study, we aimed to characterize the gut microbiome and its potential functioning in 2 populations at 2 time points during pregnancy in relation to mental distress. Methods: During the second and third trimester, individuals from the United States and Sweden completed the Edinburgh Postnatal Depression Scale and provided fecal samples for whole-genome metagenomics. A total of 832 and 161 samples were sequenced and analyzed from the Swedish cohort and the U.S. cohort, respectively. Multiple characterizations of the microbial community were analyzed in relation to distress measured using the Edinburgh Postnatal Depression Scale. Principal coordinate analysis and distance-based redundancy analysis assessed variation in functional gut-brain modules. For the U.S. cohort, the Trier Social Stress Test was administered 8 weeks postpartum while collecting salivary cortisol. Results: Principal coordinate analysis identified 4 sample clusters based on the gut-brain modules distinguished by functions such as short-chain fatty acid synthesis and cortisol degradation. While with distance-based redundancy analysis, mental distress subtypes did not significantly contribute to variation in gut-brain modules ( Conclusions: Further studies are warranted to investigate the potential for the gut microbiome to serve as biomarkers of gut-brain axis health during pregnancy across disparate populations.
