Insurance coverage and provision of opioid disorder treatment: Evidence from Medicare.
Article in Journal of policy analysis and management : [the journal of the Association for Public Policy Analysis and Management], 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
Older adult opioid overdose deaths have increased over the past two decades in the United States. Methadone, one of three medications approved for opioid use disorder (OUD) treatment, was not covered by Medicare - the primary insurer of older Americans - for OUD until 2020. We study the response of opioid treatment programs (OTPs), the only healthcare providers that can dispense methadone for the treatment of OUD in the U.S., to this policy change using administrative data and a difference-in-differences framework. We find an increase in Medicare acceptance by OTPs and in the number of methadone treatment episodes post-policy. Further, we document spillovers to other insurance markets and changes in (non-methadone) treatment services offered by OTPs, suggesting that Medicare's entrance into this market has implications for all OUD patients receiving methadone treatment in OTPs.
