The Relationship Between Methadone and Buprenorphine Enrollment and Overdose Prevention and Treatment Behaviors Among a Community Sample of People Who Use Opioids in Baltimore, Maryland.

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
backgroundMethadone and buprenorphine can reduce overdose-related mortality. Behavioral approaches can also reduce fatal overdoses. The current study examined the relationship between methadone and buprenorphine and overdose history and overdose prevention and treatment behaviors.
methodsBetween December 2022 and August 2024, 647 individuals who used opioids in the prior month enrolled in a community recruited study on overdose. Participants were administered a face-to-face survey. Key behaviors assessed included overdose recency, testing drugs for potency, ingesting drugs slowly, using fentanyl test strips, using drugs alone, and carrying naloxone. Chi-square and logistic regression models examined the relationships between methadone and buprenorphine and overdose-related outcomes.
resultsIn total, 32.9% of participants were currently taking methadone and 15.5% buprenorphine. Most (69.2%) reported ever overdosing, and among those, 33.7% had overdosed within the prior 6 months. There were no significant associations between methadone or buprenorphine status and overdose prevention and care behaviors. In the multivariable logistic regression model, methadone use was associated with a lower odds ratio (aOR = 0.49, 95% CI = 0.30-0.79of a recent overdose compared to buprenorphine. Daily or almost daily crack use was associated with greater odds of a recent overdose (aOR = 2.21, 95% CI = 1.44-3.39. DISCUSSION: Findings suggest the importance of promoting overdose prevention and care behaviors to people in drug treatment and training them to promote overdose prevention and care behaviors among their drug-using network members and other community members.
