Physical activity, social support, and working memory in older adults: evidence from a Chinese sample.
Article in Frontiers in psychology, 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
This study examined the associations between physical activity (PA), social support and working memory performance in older adults. With a particular focus on the potential moderating role of social support. Using a cross-sectional design, we recruited 123 community-dwelling older adults who completed assessments of PA (MET-min/week), social support (SSRS total score), and working memory performance across 0-back, 1-back, and 2-back conditions. After standardizing PA and SSRS, an interaction term was constructed. Hierarchical regression analyses were conducted after standardizing variables, with age, sex, and education controlled. The results indicated that both PA and social support were positively associated with 2-back accuracy, while no significant associations were observed for 0-back or 1-back performance. A significant moderating effect of social support was observed, such that the association between PA and working memory was stronger at higher levels of social support. These findings suggest that higher levels of physical activity and social support are associated with better high-load working memory performance, and that social support may enhance the cognitive benefits of physical activity in older adults.
