Geographic variation in Medicare Advantage nonemergency medical transportation benefits 2020-2024.
Article in Health affairs scholar, 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
Introduction: Nonemergency medical transportation (NEMT) is a supplemental benefit in Medicare Advantage (MA) plans that helps individuals overcome transportation barriers to healthcare services. It remains unclear whether these benefits are targeted to communities with greater needs. Methods: We analyzed MA plan benefit data from 2020 to 2024 across 2764 US counties. Transportation barriers were assessed using 5 indicators: vehicle ownership, income levels, self-reported health status, avoidable hospital visits, and access to primary care. We examined trends in NEMT availability and its alignment with county-level transportation need, considering MA plan penetration as a modifying factor. Results: Nonemergency medical transportation benefit prevalence in MA plans increased by 13.88% points from 2020 to 2024. In 2024, counties with the greatest transportation barriers had a 19.4% point higher prevalence of NEMT offerings compared to counties with the fewest barriers. Alignment was stronger in counties with higher MA plan penetration. Conclusion: Medicare Advantage plans increasingly offer NEMT benefits in areas with greater transportation challenges, especially where MA plan penetration is higher. These findings suggest responsiveness to social needs and the potential role of market dynamics. Policymakers can support equitable access by incorporating transportation needs into MA plan evaluations.
