A digital mindfulness intervention improves sleep efficiency and heart rate variability in healthy adults.
Trial report in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07469644 (A Digital Mindfulness Intervention to Improve Sleep Efficiency and Heart Rate Variability in Healthy Adults), which is not on this 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.

Abstract
To test whether a 10-day mindfulness program delivered through the ŌURA app improves sleep and stress in healthy adults, eighty-one adults were randomized to mindfulness (n = 49) or waitlist control (n = 32). Participants wore an Ōura ring during baseline, intervention/wait-list, and 4-week follow-up, recording sleep efficiency, total, deep, and light sleep, plus sleep-onset time. Questionnaires-Pittsburgh sleep quality index (PSQI), perceived stress scale (PSS), Copenhagen burnout inventory (CBI), and mindful attention awareness scale (MAAS)-were completed pre- and post-intervention and at follow-up. Mixed-model ANOVAs revealed significant group × time interactions for sleep efficiency, total sleep, deep and light sleep, and sleep-onset time (all ps < 0.031). Results showed that the mindfulness group improved after 10 days (all ps < 0.021); gains persisted at follow-up except for deep sleep. The mindfulness group exhibited increased personal burnout (p = 0.021) immediately post-intervention, though this returned toward baseline at follow-up. In addition, the mindfulness showed higher MAAS scores (p = 0.017). During mindfulness sessions heart rate fell (p = 0.011) and heart-rate variability rose (p = 0.029). A brief, app-based mindfulness program produced sustained improvements in sleep efficiency and enhanced HRV, demonstrating that digital mindfulness can favorably influence biobehavioral sleep-stress metrics.Trial Registration: ClinicalTrials.gov: NCT07469644.
