Medicare Part D beneficiaries' self-reported barriers to switching plans and making plan comparisons at all.
Article in Health affairs scholar, 2024. 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
In the United States, individuals with disabilities and those aged ≥65 can supplement their Medicare with so-called stand-alone Medicare Part D prescription drug plans. Beneficiaries can switch their stand-alone prescription drug plans annually, but most do not. Indirect evidence has raised concerns that non-switchers do not even make plan comparisons (labeled "inattention"), but direct evidence is scarce. Therefore, we surveyed 439 beneficiaries of Medicare Part D plans from a nationally representative adult sample after the 2024 open-enrollment period. Overall, 53% self-reported making no comparisons. Of those who did not compare, 98% did not switch (vs 67% of those who did compare). Multinomial regressions revealed that beneficiaries who neither compared nor switched were more likely than switchers to report difficulties with comparing and switching, experiencing no plan-related discontinuation, changes, or dissatisfaction, not using advisors or the plan-finder website, and receiving potentially confusing mailings. Non-switchers who did compare were similar to switchers in reporting few difficulties and relying on advisors and the plan-finder website, but they were less likely than switchers to report plan-related changes, discontinuation, or dissatisfaction, while being more likely to report receiving mailings and having no college degree. We discuss insights for policy-making.
