Associations Between Social Jetlag and Gut Microbiome Profiles in Adolescents.
Article in Nature and science of sleep, 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
Background: The microbiota-gut-brain axis plays a vital role in health, with growing evidence linking SJL to the gut microbiome. In this study, the relationship between self-reported SJL and gut microbiome composition is evaluated in an adolescent population. Methods: A total of 120 healthy adolescents (69 females, 51 males; mean age 12.69±0.65 years) were included. We investigated the associations of self-reported SJL with gut microbial α-diversity, the Firmicutes/Bacteroidetes (F/B) ratio, specific bacterial taxa, and functional gene diversity. Results: Participants had an average SJL of 0.87±0.73 h, with 25.0% experiencing SJL ≥2 h/d. Although continuous SJL was negatively correlated with α-diversity at the family level (Shannon and Simpson indices, all Conclusion: SJL is associated with shifts in functionally relevant gut taxa, rather than a global ecological restructuring, in adolescents. Future work is needed to decipher the mechanisms of this microbiome-SJL interaction and its health significance.
