Among Medicare beneficiaries, Affordable Care Act coverage expansions reduced utilization of ambulatory care, particularly among duals.
Article in Health affairs scholar, 2024. 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
We leveraged local area variation in the size of the Affordable Care Act (ACA) expansions of Medicaid and nongroup coverage and measured changes in Medicare utilization and spending from 2010 through 2018 using the universe of Medicare fee-for-service claims. We found that the ACA coverage expansions led to decreases in the share of Medicare beneficiaries receiving ambulatory care and decreases in spending per beneficiary on ambulatory care. The reductions in ambulatory care were larger among beneficiaries enrolled in both Medicare and Medicaid ("duals"). Our results suggest that coverage expansions may lead to congestion and reduced access to physicians for those who are continuously insured.
