Real-time digital assessment of sleep-cognition dynamics in dementia care dyads.

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
introductionSleep disturbance is common in persons living with dementia (PLWD) and may contribute to day-to-day variability in cognitive functioning, with implications for daily activities and caregiving. However, traditional cognitive assessments may not capture these short-term fluctuations. Ecological momentary cognitive testing (EMCT) enables repeated, real-world assessment of cognitive performance. This study examined day-to-day associations between sleep and cognitive performance in PLWD-caregiver dyads.
methodsBaseline data from PLWD-caregiver dyads enrolled in a behavioral sleep trial were analyzed. PLWD completed smartphone-based EMCT tasks assessing processing speed and response inhibition three times daily for 7 days, along with the Mini-Mental State Examination (MMSE). Caregivers reported daily sleep outcomes for themselves and PLWD. Pearson correlations and mixed-effects models adjusted for PLWD age, gender, education, and phone type.
resultsEMCT performance correlated significantly with MMSE scores ( DISCUSSION: EMCT captured within-person, time-varying associations between dyad sleep and cognitive performance in PLWD, highlighting its utility for identifying daily fluctuations relevant to functioning and caregiving. These findings support digital, dyadic approaches to monitoring sleep and cognitive function in dementia care.
