Physical function domain associations with cognitive domains in community-dwelling older adults.
Article in medRxiv : the preprint server for health sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Physical and cognitive aging do not occur uniformly, yet associations between specific physical function and cognitive domains in sedentary older adults remain unclear. This exploratory cross-sectional study examined associations between multiple physical function domains and cognitive outcomes in sedentary, community-dwelling, cognitively unimpaired older adults. Methods: Fifty-eight older adults (70.7±4.7 years; 84.5% Female) completed handgrip strength, 30-second chair stand, timed up and go (TUG), brisk walk, and 6-minute walk (6MWT) assessment. Cognitive outcomes included global cognition using the Montreal Cognitive Assessment (MoCA), and working memory, episodic memory, attentional inhibition, and cognitive flexibility using the NIH Toolbox. Linear regression models adjusted for age, sex, education, body mass index, and brachial pulse pressure. False discovery rate (FDR) correction was applied. Results: Greater 6MWT distance was associated with better episodic memory performance after FDR correction ( Conclusions: These exploratory findings suggest that locomotor-based functional tasks may demonstrate stronger cognitive associations than strength measures in sedentary, cognitively unimpaired older adults. Tasks involving sustained locomotion and adaptive movement may place greater cognitive-motor demands, potentially increasing sensitivity to subtle cognitive variation. Larger longitudinal and multimodal studies are needed to determine whether these associations reflect reliable differential patterns across physical and cognitive domains.
