Health access and prevention under Arkansas' market-based Medicaid expansion.
Article in Health affairs scholar, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Arkansas expanded Medicaid in 2014 using a Section 1115 waiver that included premium assistance for beneficiaries to purchase private plans through the state's marketplace. The waiver was modified in 2017 to require partial premium payments and implemented work requirements in mid-2018, which were later rescinded by federal court order. We compared healthcare access and preventive service utilization in Arkansas vs states with traditional Medicaid expansions. Methods: Using Behavioral Risk Factor Surveillance System data from 2011 to 2021, we applied difference-in-differences analysis to examine low-income non-elderly adults aged 18-64 in Arkansas and 3 demographically similar traditionally expanding states (Kentucky, Ohio, West Virginia). Outcomes included insurance coverage, usual source of care, annual checkups, cost-related care avoidance, and flu vaccination. Results: Compared to traditional expansion states, Arkansas' expansion was associated with greater increases in insurance coverage (+3.5% points, Conclusion: Pre-existing gaps between Arkansas and traditional expansion states narrowed for insurance coverage and rates of annual checkups, while other outcomes improved in Arkansas at levels comparable to those observed in traditional expansion states.
