A proper combination of movement and stillness: the interaction effect of sleep duration and physical activity on longitudinal cognitive performance in Chinese middle-aged and older adults.
Article in GeroScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Previous studies have shown that both nighttime sleep duration (NSD) and physical activity (PA) are independently associated with geriatric cognition. However, most of these studies are cross-sectional and do not account for the interaction between NSD and PA, and the relationship between midday nap duration (MND) and cognition is unclear. Data collected between 2011 and 2018 were obtained from the China Health and Retirement Longitudinal Study (CHARLS). Generalized linear models and generalized estimating equations were used to analyze the impacts of NSD, MND, total sleep duration (TSD, NSD + MND), PA, and their interactions on both baseline and longitudinal cognitive performance. Combining the results of baseline and longitudinal univariable analyses, inverted U-shaped patterns were found, with the best choices being the 6-8 h of NSD and TSD (P < 0.05), the 0-90 min of MND (P < 0.05), and moderate PA (MPA, P < 0.05). The interaction analysis revealed that individuals with sleep duration of 6-8 h or < 6 h who engaged in MPA demonstrated significantly better cognitive performance and maintenance (P < 0.05), but for those with > 8 h of sleep, little significant differences in cognitive outcomes were observed across varying PA regimens. Considering both univariable and interaction effects, an optimal combination of movement and stillness for better cognitive function is to maintain 6-8 h of nighttime sleep, take a midday nap, and actively engage in MPA.
