Day-to-day sleep efficiency and driving behaviors in older adults with and without cognitive impairment.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). 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
introductionSleep disturbances are common in older adults, particularly those with cognitive impairment. This study examines how day-to-day sleep quality impacts real-world driving behaviors, offering insight into sleep as a potential functional biomarker of cognitive health.
methodsWe monitored 149 community-dwelling older adults (90 cognitively impaired, 59 unimpaired) over 12 weeks. Sleep was measured via wrist-worn actigraphy, and driving data were collected via an in-vehicle sensor system. A zero-inflated Poisson regression model examined whether sleep efficiency was associated with next-day driving likelihood and frequency, and whether these relationships varied by cognitive status.
resultsBetter sleep efficiency increased the likelihood of driving the next day more for cognitively impaired participants than for unimpaired participants. Higher sleep efficiency was associated with increased driving frequency in both groups. DISCUSSION: These findings underscore the importance of daily sleep variability as a potential digital biomarker for functional abilities in older adults, highlighting opportunities for early intervention to preserve mobility and independence. Highlights: A 1 standard deviation increase in sleep efficiency increases next-day trip counts (incidence rate ratio = 1.014).In cognitively impaired participants, better sleep lowers the odds of not driving the next day (odds ratio = 0.877).Among those who choose to drive, trip counts do not differ by cognitive status.
