Rest-Activity Rhythms and Cognition in Older Adults With and Without Insomnia.

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
Insomnia is associated with risk for cognitive deficits. However, the literature assessing cognitive impairments in insomnia is replete with conflicting findings; it is unclear whether individuals with insomnia exhibit impaired cognition or whether specific sleep features consistently predict cognitive performance in insomnia. Disturbance in rest-activity rhythms may be more directly associated with cognitive deficits in insomnia. In a sample of older adults with (n = 30) and without insomnia (n = 33), we examined (1) whether insomnia diagnosis was associated with differences in rest-activity rhythms and cognition, and (2) whether rest-activity rhythms were associated with cognition across domains. We used a remote comprehensive cognitive battery to test four domains of cognition: attention, inhibition, cognitive flexibility, and episodic memory. Compared to older adults without insomnia, older adults with insomnia exhibited attenuated rest-activity rhythms, indicated by lower relative amplitude (F
