Association between physical activity levels, sedentary time, and mild cognitive impairment in older adults.
Article in Frontiers in public health, 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
Background: Research indicates that mild cognitive impairment (MCI) in older adults is associated with physical activity levels (PAL) and sedentary behavior duration. However, the precise nature of the relationships between these factors and MCI warrants further investigation. Methods: A cross-sectional survey was conducted from August to October 2025 using cluster sampling in community settings, involving 1,465 older adults. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). PAL were assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), while sedentary time was self-reported. Logistic regression models were employed to analyze the associations between PAL, sedentary time, and MCI. Restricted cubic spline (RCS) analysis was used to further explore the dose-response relationships. Sensitivity analyses were also performed to validate the observed associations. Results: Logistic regression analysis revealed that the second and fourth quartiles of PAL (vs. the first quartile) were associated with a significantly reduced risk of MCI ( Conclusion: Both physical activity and sedentary time are closely associated with the incidence of MCI in older adults. Maintaining a weekly PAL between 1,485 and 4,000 MET-min/wk. and limiting daily sedentary time to under 200 min may help reduce the risk of MCI.
