Theme recognition and evolutionary analysis of older adults cognitive disorder prevention and control policies based on the BERTopic model.
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
Introduction: The early diagnosis and treatment of mild cognitive impairment (MCI) can help decelerate or even reverse the progression of dementia. Therefore, China attaches great importance to the prevention and control of MCI and has introduced a series of policies. Methods: Policy themes were identified by pre-processing, vectorizing, and clustering relevant policy texts by using the BERTopic model, and their temporal evolution patterns were revealed through dynamic topic modeling. Results: Central-level policies on cognitive impairment prevention and control encompass 12 themes, which can be classified into three major categories: community prevention and early screening, multistakeholder participation in rehabilitation work, and collaborative high-risk chronic disease management. Different work priorities were observed during the initial budding (2005-2018), progressive consolidation (2019-2023), and rapid development (2024-present) stages. Policies consider comorbidity management and demonstrate simultaneous systematization and refinement, with the focus of prevention and control gradually moving forward and responsibilities becoming increasingly diversified. However, issues, such as an underdeveloped comorbidity management system, insufficient coordination between central and local authorities, poor linkage between stages, and inadequate multistakeholder collaboration, persist. Discussion and implications: In the future, constructing cognitive impairment prevention and control implementation pathways tailored to local resources; establishing policy transition mechanisms; improving multidepartment and multistakeholder collaboration networks; and enhancing the role of personnel in early screening, rehabilitation interventions, and comorbidity management are necessary to promote effective policy translation and implementation.
