Multidimensional sleep health is associated with mild cognitive impairment in older adults: a cross-sectional study.
Article in Frontiers in public health, 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: Mild cognitive impairment (MCI) is a transitional stage preceding dementia and may be amenable to early intervention. Although sleep problems are common among older adults and related to cognitive function, most studies have focused on single sleep characteristics rather than multidimensional sleep health. Methods: This cross-sectional study included 416 adults aged ≥ 60 years from three nursing homes and two communities in Wuhan, China. Sleep health was assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) to measure the five SATED sleep dimensions. Cognitive function was evaluated using the Montreal Cognitive Assessment Basic Version. Group comparisons and binary logistic regression analyses were used to examine associations between sleep health indicators and prevalent MCI. Results: Overall, 197 participants (47.35%) had MCI, and 294 (70.7%) had unfavorable sleep health in at least two SATED-based dimensions. The non-MCI group had a higher composite sleep health score than the MCI group (Z = -5.051, Conclusion: Better multidimensional sleep health was associated with lower odds of prevalent MCI among older adults. Longitudinal studies are needed to confirm these findings.
