Sleep hygiene mediates anxiety and sleep quality in adults: mediation and network analysis.
Article in BJPsych open, 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
backgroundSleep hygiene plays a crucial role in mental well-being, yet its influence on the relationship between anxiety and sleep quality in young adults remains underexplored.
aimsThis study examines whether sleep hygiene mediates the bidirectional association between anxiety and sleep quality, identifying key behavioural targets for intervention.
methodA cross-sectional study was conducted with 405 randomly selected college students who completed validated assessments of sleep hygiene, anxiety and sleep quality. Mediation and network analyses were employed to investigate the underlying mechanisms.
resultsSleep hygiene significantly mediated the relationship between anxiety and sleep quality, emphasising the role of consistent sleep-wake schedules. Network analysis identified irregular sleep patterns and specific sleep quality components - wakefulness behaviours, sleep initiation and self-reported sleep quality - as primary factors.
conclusionThese findings highlight sleep hygiene as a modifiable, non-pharmacological strategy to mitigate anxiety and improve sleep quality. Future research should explore longitudinal interventions.
