Wealth, income and dementia in Germany: longitudinal findings from a representative survey among the oldest old.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThere is limited knowledge on the link between wealth, as well as income, and dementia risk among the oldest old (80 years and over). The purpose of our study was to examine the association between income, wealth, and dementia among the oldest old in Germany.
methodsWe used representative longitudinal data from a survey, which aimed to assess the quality of life and subjective well-being of individuals aged 80 years and above in North Rhine-Westphalia (Germany). The length of follow-up was approximately 2 years. The sample consisted of both community-dwelling and institutionalized individuals, with a total of 943 observations included in the analysis. The average age of the participants was 86.0 years (SD: 4.0 years). Probable dementia was assessed by DemTect, a widely accepted screening instrument. Common income and wealth categories were used to quantify these variables.
resultsAfter adjusting for sociodemographic and health variables, logistic random effects regressions showed that greater wealth was associated with a lower likelihood of probable dementia (second lowest wealth quartile compared to lowest wealth quartile: OR: 0.23, 95% CI: 0.07-0.76; second highest wealth quartile: OR: 0.05, 95% CI: 0.01-0.31; highest wealth quartile: OR: 0.12, 95% CI: 0.02-0.91). In contrast, income was not significantly associated with the likelihood of probable dementia.
conclusionOur study showed a link between wealth and dementia. Such knowledge can enrich poverty and inequality research within this field. More specifically, our findings lend support to evidence-based policies aiming to decrease the burden of dementia in later life through reduction in economic inequalities and better income distribution.
