Sleep Quality of Persons with Dementia and Family Caregivers in Korean Americans: Wearable Technology to Study the Dyadic Association.
Observational study in Western journal of nursing research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 disturbances, such as difficulty in falling asleep and multiple awakenings at night, are prevalent among persons with Alzheimer's disease and related dementias (hereafter dementia), resulting in advanced cognitive impairment and increased behavioral problems. Additionally, family caregivers (eg, spouses or offspring) suffer from reduced sleep quality as a result of sleep disturbances in the persons with dementia (PWDs) they care for. Relatively little is known about the interaction of sleep parameters in dyads (PWD-caregiver) as paired units among understudied immigrant minorities, particularly Korean Americans.
objectivesTo describe dyads' sleep parameters (ie, total/deep/rapid eye movement/light sleep, awake duration, latency duration, sleep efficiency) using wearable technology (smart-rings) and sleep diaries, and to identify interrelationships among sleep parameters between PWD and caregivers.
methodsThis 4-week observational study used smart-ring monitoring, a sleep survey, and self-reported sleep diaries to explore sleep associations of Korean American dyads recruited from the community. Pearson correlations were performed.
resultsA total of 11 dyads participated in the study. The mean age of PWD was 82.7 years (standard deviation (SD) = 2.3); of caregivers 69.1 years (SD = 10.2). Nine PWD (81.8%) were male, all caregivers (100%) were female, and 4 dyads (36.4%) slept in the same bed. Sleep parameters of PWD were significantly correlated with those of caregivers.
conclusionOur findings demonstrate that PWD's sleep parameters (eg, deep sleep) were significantly correlated with those of caregivers' parameters. This study shows the feasibility of using wearable device to measure dyadic sleep quality for both PWD and their caregivers, particularly within immigrant populations.
