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
introductionSpatial and social-environmental factors influence individual cognition and dementia risk, but the role of social infrastructure in geographic dementia disparities remains underexplored.
methodsWe used 2020 Medicare claims data from the Dementia DataHub and 2003-2017 business and establishment data from the National Establishment Time Series Database in spatial autoregressive models to examine associations between county-level social infrastructure and county-level dementia rates.
resultsHigher densities of civic organizations were associated with lower county dementia incidence, while museums and recreational facilities were associated with lower prevalence and incidence. Religious organizations were associated with significantly higher rates. County urbanicity moderated the effects of recreational facilities, senior centers, libraries, and coffee shops. DISCUSSION: Types of social infrastructure may help address dementia and related needs by providing social, educational, and other cognitively-protective resources to county residents. Social infrastructure warrants further attention as an area for local investment to reduce geographic disparities in dementia.
