American's overall and equity-based societal valuation of a disease-modifying Alzheimer's treatment: Results from a discrete choice experiment.
Article in The journal of prevention of Alzheimer's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesTo estimate Americans' willingness-to-pay (WTP) for universal access to a disease-modifying Alzheimer's disease (AD) treatment with a discrete choice experiment in a nationally representative sample. As part of this experiment, we examined whether providing information about the higher disease burden among minorities and persons of lower socioeconomic status (SES) changes WTP.
methodsWe conducted an information experiment using the nationally representative Understanding America Study (UAS) panel. Participants were provided with general information about AD and a hypothetical treatment that reduces disease progression by 30 %. Two-thirds of the sample were randomized to receive additional information about the higher prevalence of Alzheimer's among either lower SES groups or racial/ethnic minorities. We measured participants' WTP for making the treatment nationally available as a fixed annual fee and income-proportionate fee. Differences in WTP between those exposed to the additional information and those who were not provide the societal valuation of the equity-enhancing effects of the AD treatment.
resultsAverage valuations were $252, $260 and $247 per year, and 0.59 %, 0.59 % and 0.61 % of earned income, for the control, race/ethnicity and SES frames, respectively-all statistically indistinguishable. These average results imply that Americans would be willing to pay $33.7 billion based on the fixed fee and $51.4 billion based on the income-related charge for universal access to an AD treatment annually, but their valuation does not further increase when informed about equity considerations.
conclusionsWhile Americans value universal access to an AD treatment highly, health equity considerations did not significantly alter respondents' WTP.
