The association between neonatal respiratory distress syndrome and gut microbiota dysbiosis: evidence from metagenomics.
Article in Frontiers in microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Neonatal respiratory distress syndrome (NRDS) is a common and life-threatening respiratory disorder that affects newborns, significantly impacting their health and survival rates. In recent years, the potential role of the gut-lung axis in NRDS has garnered increasing attention; however, the specific mechanisms involved remain unclear. This study aimed to investigate the association between NRDS and gut microbial composition and functional profiles using shotgun metagenomic sequencing. Methods: This case-control study recruited 25 infants diagnosed with NRDS and 15 healthy newborns, all aged between 2 and 6 days. Fecal samples were collected from all participants for subsequent metagenomic sequencing and bioinformatics analysis. Results: There was no significant difference in α-diversity between the NRDS group and the control (CON) group ( Conclusion: NRDS was associated with differences in gut microbial composition and shotgun-metagenomic functional profiles. These preliminary findings characterize group-level microbial differences but do not establish whether the observed alterations preceded or resulted from NRDS. Longitudinal studies are required to clarify their temporal relationship and clinical relevance.
