Trends and Disparities in Dementia Among Older Adults With Coronary Artery Disease, 1999-2023: Insights From the CDC WONDER Database.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionDespite growing multimorbidity rates, older adults, particularly those with dementia, remain underrepresented in cardiovascular research. Most research on CAD excludes individuals with cognitive impairment, leaving a gap in our understanding of how dementia and CAD affect mortality. This study bridges that gap by examining 25-year nationwide trends in dementia and CAD-related mortality among elderly in the United States.
methodsWe performed a descriptive trend analysis using Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) Multiple Cause-of-Death data (1999-2023). Deaths with International Classification of Diseases, 10th Revision (ICD-10) codes I20-I25 (CAD) and F01, F03, G30 (dementia) were included if either appeared anywhere on the death certificate. Age-adjusted mortality rates (AAMRs) per 100,000 population were calculated and stratified by sex, race/ethnicity, state, census region, place of death, and urban/rural status. Average AAMRs were calculated by using the AVERAGE Excel function for the entire study period. Joinpoint regression with annual percentage change (APC), average APC (AAPC), and 95% confidence intervals (CIs) were used to evaluate temporal changes. The threshold for statistical significance was set at p < 0.05.
resultsIn adults aged ≥65 years, dementia with CAD was the cause of 1,256,284 deaths between 1999 and 2023. More than half took place in long-term care institutions. Overall, the AAMR trend showed no statistically significant change (AAPC: -0.23; p = 0.325). The average AAMRs of males were greater than those of females (127.75 vs. 109.83). Non-Hispanic (NH) Whites had the highest average AAMRs (121.59). Regionally, average AAMRs were highest in the Midwest (123.02), followed by Northeast, South, and West. Average AAMRs were highest in rural areas (129.73 vs. 117.12 in urban areas) with a statistically significant upward trend in rural AAMRs (AAPC: 1.16; p < 0.001), whereas urban rates remained stable. Subgroup analysis revealed highest mortality burden associated with vascular dementia-related CAD (AAPC = 8.49).
conclusionAmong the elderly, dementia with CAD continues to cause significant mortality in the United States, particularly in males, rural regions, and long-term care settings. These findings highlight an urgent need for inclusive cardiovascular research and health care personalized to this often-overlooked population.
