Public transit and methadone - Spatial analyses of opioid treatment program access in Greater Boston, 2020-2022.
Article in Preventive medicine reports, 2025. 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
Objective: Methadone, an FDA-approved medication, can effectively treat opioid use disorder (OUD). However, long travel times to opioid treatment programs (OTPs) commonly present barriers to initiating and continuing methadone treatment. We utilized geographic information systems to identify areas with unmet OTP access needs via public transportation and walking in Boston, Massachusetts. Methods: We created public transit-time and walk-time catchment areas around OTPs. We assessed spatial overlap between the catchment areas and locations of opioid-related overdose decedent residences from 2020 to 2022 in Boston, and inequities in OTP access by decedent race/ethnicity using logistic regression. Results: In Greater Boston, 50.1% of fatal opioid-related overdose decedent residences were within 30 min of an OTP via public transit at the time of death. In Boston, 80.4% of fatal opioid-related overdose decedent residences were within 30-min transit times of an OTP. In the early morning, access to OTPs on public transit is limited. Differences in OTP access based on decedent race/ethnicity were inconsistent. Conclusion: Many areas in Greater Boston have unmet OTP access needs on public transit. Our results can inform decision-making to improve OTP access in Boston, such as increased early-morning transit service, expanding access to methadone beyond existing OTPs, or broadening non-emergent medical transit.
