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
backgroundAging is accompanied by declines in cognitive, sensory, and motor functions that can adversely affect everyday activities, such as walking while performing a concurrent cognitive task. In this study, we investigate the effects of age and age simulation on dual-task performance, specifically focusing on gait and memory.
methodsWe compare three groups: young adults (n = 28, Mage = 21.82, SDage = 1.96), young adults wearing an age simulation suit (n = 28, Mage = 22.07, SDage = 1.51), and older adults (n = 28, Mage = 72.82, SDage = 6.74). Participants performed a 2-minute walking test (walking as fast as possible) and a word memory test (learning words presented on a piece of cardboard) under single- and dual- task conditions (repeated measures). Gait parameters, including walking speed, cadence, stride length, and double-support time were recorded using a wearable motion capture system. Mixed-design ANOVAs were conducted with Group as a between-subjects factor and Task Condition as a within-subjects factor.
resultsThe analyses revealed significant main effects of Task Condition, indicating impairments in both cognitive and gait performance under dual-task conditions (both p < .001), as well as significant main effects of Group, with older adults exhibiting the poorest performance overall (both p < .001). Notably, while memory performance did not differ significantly between young adults with and without the age simulation suit (p = .729), the suit resulted in significantly slower gait speed (p < .001) and alterations in other gait parameters approximating older adults' gait profiles.
conclusionsThese results underscore that declines in central attentional capacity combined with peripheral deficits contribute to dual-task interference, potentially increasing instability and fall risk in older populations. Importantly, the group differences reveal how these mechanisms contribute in different ways to age-related performance declines.
