Prevalence and Risk Factors of Dementia Among Older People of Gelao Ethnicity in China: A National Cross-Sectional Study.
Article in CNS neuroscience & therapeutics, 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
aimsApproximately 96% of the Gelao population lives in Guizhou Province, predominantly in Wuchuan and Daozhen counties. This study explored the prevalence of dementia and the factors associated with it among the Gelao ethnic group in this area.
methodsA stratified random cluster sampling method was used to conduct a face-to-face questionnaire survey with Gelao individuals aged ≥ 65 years from August to October 2022. The survey collected data on demographics, medical history, lifestyle, and dietary habits. Participants were assessed using the Chinese Mini-Mental Status Examination (CMMS) and the Activities of Daily Living (ADL) scale. Dementia diagnoses were made according to DSM-IV-TR criteria.
resultsAmong the 2712 participants, the prevalence of dementia was found to be 24.74% (95% CI: 23.1-26.4). Multivariable analysis indicated that factors such as not residing in a nursing home, maintaining good tooth brushing habits, engaging in physical activity, visiting the market, playing mahjong, having a high income, drinking oil tea, and consuming Houttuynia cordata were associated with lower odds of dementia (all p < 0.05).
conclusionThe prevalence of dementia among older Gelao adults is notably high, especially among women. These results underscore the urgent need for targeted awareness campaigns, screening initiatives, and intervention strategies aimed at alleviating the dementia burden within this ethnic minority population.
