Finding fraud: enforcement, detection, and recoveries after the ACA.
Article in International journal of health economics and management, 2023. 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
Medicaid Fraud Control Units investigate and prosecute acts of financial fraud and patient abuse within the program. Prior to the expansion of Medicaid under the Affordable Care Act (ACA), federal government MFCU expenditures totaled half a percent of Medicaid expenditures. Following the enrollment of 12 million adults into the Medicaid program under the ACA, expenditures for these units are now less than pre-ACA levels, as a share of program expenses. We use data for states' fraud enforcement efforts in the period 2010-2018 and a difference-in-differences design that exploits states' decision to expand Medicaid under the ACA. States that did expand Medicaid increased their fraud investigations, compared to states that did not expand. Further, civil recoveries and excluded individuals increased after the Medicaid expansion. We find evidence that increases in program scale, in terms of enrollment and utilization, reverted to the mean, facilitating the identification of outlier provider behavior.
