Chronic stress, social support, and domain-specific cognitive decline in HABS-HD.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 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
introductionFew studies have examined the longitudinal associations between chronic stress, social support, and cognitive decline or whether sociodemographic factors modify associations.
methodsWe included 3873 older adults enrolled in the Health and Aging Brain Study-Health Disparities (HABS-HD). Longitudinal mixed-effects models were used to examine associations of baseline chronic stress and social support with changes in domain-specific cognitive z-scores (attention, memory, executive functioning, language). Interactions between baseline chronic stress or social support and gender or race/ethnicity in relation to cognitive decline were also assessed.
resultsHigher baseline chronic stress was associated with greater decline in attention and language for women compared to men and greater decline in memory for Hispanics compared to non-Hispanic Whites. Higher baseline social support was associated with less decline in attention; results did not differ by gender or race/ethnicity. DISCUSSION: Sociodemographic factors warrant consideration when examining associations of chronic stress or social support with cognitive decline.
