1 · What the graph read from it

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.

2 · The registry

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

backgroundForced displacements may increase overdose risk among people who use drugs (PWUD) through disruptions to naloxone, safer drug use supplies, and substance use disorder (SUD) treatment access. We investigated whether forced displacements were associated with nonfatal overdose, naloxone access, and SUD treatment access among PWUD in San Francisco, California.

methodsWe conducted a cross-sectional survey of 790 PWUD from September 2024 to September 2025. Participants reported number of forced displacements by police, security guards, or other officials in the past 3 months. Outcomes included past 3-month overdoses, naloxone access, and SUD treatment. We conducted separate multivariable modified Poisson models with robust standard errors for each outcome, adjusting for age, gender, race, housing status, past 3-month opioid use, and interviewer.

resultsIn the past 3 months, 70% of participants were forcibly displaced at least once and 36% were displaced 20 or more times. Of those forcibly displaced at least once, 65% had their belongings taken by those displacing them. Eleven percent experienced an overdose; 62% were provided with naloxone; 33% received any SUD treatment, and 18% were currently receiving any treatment. Those forcibly displaced 20+ times had 1.99 times the prevalence of overdose of non-displaced participants (95% confidence interval [CI]: 1.01-3.93). Participants who had their belongings taken had 1.59 times the prevalence of nonfatal overdose of those who did not (95% CI: 1.00-2.53). There was no association between forced displacements and receiving any SUD treatment, but participants who were forcibly displaced 20+ times had a lower prevalence of currently receiving any treatment (adjusted prevalence ratio = 0.44, 95% CI: 0.27-0.72).

conclusionsOur findings demonstrate forced displacements have significant health harms and negatively affect treatment services. Forced displacement policies should be replaced with public health approaches that prioritize stability, housing, and supportive services.
