Racial and Ethnic Differences in Long-Term Outcomes among Individuals with Opioid Use Disorder at Opioid Treatment Programs.
Trial report in Journal of racial and ethnic health disparities, 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
objectivesRacial and ethnic differences in long-term outcomes associated with medications for opioid use disorder (MOUD) are poorly understood.
methodsThe present analyses were based on 751 participants with opioid use disorder (OUD) who were initially recruited from opioid treatment programs located in California, Connecticut, Oregon, Pennsylvania, and Washington and participated in a randomized controlled trial and at least one follow-up interview. 9.6% (n = 72) of the participants self-identified as Non-Hispanic (NH) Black, 16.0% (n = 120) Hispanic, and 74.4% (n = 559) NH White. We tested racial and ethnic differences in psychiatric or social functioning, substance use and treatment participation.
resultsFrom the baseline to the end of follow-up interview, compared with NH White, Hispanic participants had a significantly greater proportion of months reporting any opioid use (45.5% vs. 32.5%, p < 0.001) and a smaller proportion of months receiving any MOUD (47.7% vs. 58.1%; p < 0.05), particularly receipt of buprenorphine treatment (8.3% vs. 14.9%; p < 0.01). At the third follow-up interview, data from the Addiction Severity Index (ASI) indicated that Hispanic participants had greater severity in employment problems (0.72 vs. 0.58; p < 0.001), while Black participants had less severity in drug problems (0.11 vs. 0.16; p < 0.05) compared to NH Whites.
conclusionsThe study found that Hispanic participants had higher rates of opioid use (heroin and prescription opioids), but few received MOUD (buprenorphine and methadone) during the follow-up period, which suggests that effective strategies are needed to increase access to MOUD among Hispanics. Additionally, addressing employment challenges might also help improve long-term outcomes for all populations with OUD.
