Associations between digital health literacy and health inequalities among middle-aged and older adults: an urban-rural disparity perspective.
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: In the digital age, digital health literacy has emerged as a critical factor influencing the physical and mental well-being of middle-aged and older adults. However, the relationship between digital health literacy and health inequalities remains underexplored. This study aims to investigate this association among middle-aged and older adults in urban and rural settings. Methods: Data were obtained from the 2021 Chinese General Social Survey (CGSS). The final analytical sample consisted of 1,672 respondents from the International Social Survey Programme (ISSP) Health Module after excluding individuals younger than 45 years and those with missing values on key variables. The digital health literacy index was constructed using the entropy weight method, which objectively determines indicator weights based on the relative information contained in each dimension. The linear probability model was employed to examine the relationship between digital health literacy and urban-rural health inequalities, given its straightforward coefficient interpretation and suitability for analyzing interaction effects. Results: Digital health literacy reduces urban-rural disparities in physical health among middle-aged and older adults by 0.2229 points [95% CI (-0.4329, -0.0129), Conclusion: Digital health literacy not only improves the physical and mental well-being of middle-aged and older adults but also effectively reduces urban-rural health inequalities.
