1 · What the graph read from it

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.

2 · The registry

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

introductionAmyloid-targeting treatments (ATT) for Alzheimer's disease require regular infusions and caregiver accompaniment for approximately 80% of patients. Travel time to infusion sites and caregiver availability can therefore impede access to care, especially in rural and lower income populations.

methodsWe conducted a survey in a nationally representative Internet panel with more than 2300 adults aged ≥65 years to estimate willingness to travel for bi-weekly infusion treatment, and access to an accompanying caregiver. Addresses of respondents and infusion sites were geocoded and driving times to the nearest infusion centers were calculated using Google Maps road network data. To estimate potential access gains under subcutaneous (SC) delivery, we estimated access by relaxing the travel and accompaniment requirements in a scenario analysis.

resultsMedian willingness-to-travel time was 97.5 minutes (interquartile range [IQR]: 67.5-187.5 minutes) one way for bi-weekly infusions over a 5-year period. Approximately 90% of respondents were willing to travel the required time to reach an infusion site. However, 18% indicated that it would be unlikely that they could identify someone to accompany them. When caregiver accompaniment was incorporated as a constraint, 75% met both the travel and caregiver criteria. In regression analysis, respondents with annual incomes above $60,000 and those residing in metropolitan areas were 9 and 19 percentage points more likely, respectively, to meet travel and caregiver criteria. In a scenario analysis, SC delivery increased overall access by up to 33%, in relative terms, with larger proportional gains for low income and rural respondents. DISCUSSION: A meaningful number of individuals in a nationally representative sample live farther from their nearest site than they would be willing to travel, and obstacles to access worsen if individuals need a caregiver to accompany them, as is common among early-stage AD patients. Treatments that do not require infusion delivery could improve equitable access to care.
