Sedentary behavior and cognitive impairment risk in older Chinese adults: effect modification by physical activity.
Article in BMC geriatrics, 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
backgroundBased on a nationally representative sample, this study aimed to analyze the association between sedentary behavior (SB) and cognitive impairment risk (CIR) among older Chinese adults, identify high-risk populations, and examine the effect modification of physical activity (PA) on this association.
methodsA total of 29,046 older adults aged 60-79 years were included from the 2025 China Sixth National Physical Fitness Surveillance database. SB and PA information were collected through structured questionnaires, and CIR was screened using the Ascertain Dementia 8 (AD8) scale. Multivariable logistic regression models were applied to analyze the association between SB and CIR, adjusting for confounding factors including sex, age, residential setting, educational attainment, geographic region, marital status, living arrangement, smoking status, and alcohol consumption. Stratified analyses were conducted to identify high-risk subgroups, and the effect modification by PA on the SB-CIR association was examined.
resultsThe overall CIR detection rate was 14.0% (4,075/29,046). After adjusting for confounding factors, using the 0-120 min/day SB group as the reference, the odds ratios (ORs) for CIR were 1.35 (95% CI: 1.23-1.48), 1.62 (1.47-1.79), and 1.89 (1.72-2.07) for SB of 120-180 min/day, 180-240 min/day, and ≥ 240 min/day, respectively, demonstrating a significant dose-response association (p < 0.001). The association was stronger among rural-dwelling and oldest-old (75-79 years) adults. Significant effect modification by PA on the SB-CIR association was observed (p for interaction = 0.02).
conclusionSB was significantly associated with CIR among older Chinese adults, and PA may modify the strength of this association. These findings suggest that rural-dwelling and oldest-old adults are populations warranting particular attention.
