Accountable care organizations and Medicare payments for residents with ADRD in disadvantaged neighborhoods.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionAccountable care organizations (ACOs) are well positioned to promote care coordination. However, robust evidence of ACOs' impact on Medicare payments for residents with Alzheimer's disease and related dementias (ADRD) in disadvantaged neighborhoods remains limited.
methodsUsing a 2016 to 2020 longitudinal dataset, we examined the effects of ACO enrollment on Medicare payments for people newly diagnosed with ADRD, focusing on the neighborhood Social Vulnerability Index (SVI) and its subcategories. Multivariable generalized estimating equation (GEE) models were applied.
resultsACO enrollment was associated with significantly reduced total payments across all SVI subcategories. The highest cost savings were observed among ADRD patients living in neighborhoods with high proportions of racial and ethnic minorities. Results also showed that higher quality ACOs were associated with lower total payments. DISCUSSION: ACOs have a great potential to save health-care costs for beneficiaries with ADRD living in socially vulnerable neighborhoods, particularly for those residing in areas with higher proportions of racial and ethnic minority populations. HIGHLIGHTS: Accountable care organizations (ACOs) reduced Medicare payments for Alzheimer's disease and related dementias across neighborhood disadvantage levels. The cost reductions varied by specific indicators of social vulnerability. Highest cost savings were found among residents living with high proportion of racial/ethnic minorities. Cost savings were the greatest among the highest quality ACOs.
