Digital divide and health status among rural older adults in China: evidence from CHARLS.
Article in Global health action, 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
backgroundDigital inequality may be associated with health disparities in rural ageing populations, yet its cognitive and social pathways and contextual conditions remain insufficiently understood.
objectivesTo examine associations between a multidimensional digital divide and health status among rural older adults in China, evaluate indirect associations through cognitive function and social participation, and assess effect modification by household broadband access and physical activity.
methodsThis was a cross-sectional secondary analysis of rural adults aged ≥60 years from the 2020 China Health and Retirement Longitudinal Study. Regression-based path models with bootstrapped confidence intervals were used to estimate total and indirect associations and interactions, with adjustment for sociodemographic covariates.
resultsA larger digital divide was associated with poorer health status. In indirect analyses, cognitive function and social participation partly accounted for the observed association. Broadband access modified the digital divide-cognition association, with a weaker negative association among those with broadband access. Physical activity modified the social participation-health association, which was attenuated at higher activity levels.
conclusionDigital inequality was associated with poorer health among rural older adults, with patterns consistent with cognitive and social pathways and variation by infrastructure and behaviour, suggesting potential targets for reducing digital health disparities.
