Encampment sweeps and persistent homelessness among unhoused people who use drugs in Vancouver, Canada: A prospective cohort study.
Article in PLoS medicine, 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
backgroundHousing is a key determinant of health. In response to increasingly visible homelessness amid a growing housing crisis, many jurisdictions in North America forcibly displace unhoused people from public spaces, routinely confiscating their personal belongings. While prior research demonstrated various health-related harms associated with these "encampment sweeps," the impact on housing placements among otherwise unhoused people remains unclear. We sought to estimate the relationship between experiencing encampment sweeps and transitioning from homelessness among unhoused people who use drugs in Vancouver, Canada. METHODS AND
findingsData were derived from two harmonized prospective cohort studies of people who use drugs in Vancouver, followed through semi-annual interviews between December 1, 2021 and May 31, 2025. We used proportional hazard marginal structural modeling (MSM) to examine if experiencing municipal government-enforced confiscation of personal belongings was associated with no longer reporting homelessness in the past 6 months during follow-up among unhoused participants after adjusting for a range of potential time-varying confounders including demographic characteristics, drug use patterns, health status and other social/structural exposures. A secondary analysis replaced confiscation of belongings with municipal government-enforced forced displacement that may have not involved confiscation of belongings between June 1, 2023 and May 31, 2025. Among 235 participants, 59 (25.1%) reported confiscation of their belongings at baseline. During follow-up, 128 (54.5%) stopped reporting homelessness, corresponding to an incidence rate of 55.6 (95% confidence interval [CI]: 46.4, 66.1) cases per 100 person-years. In the secondary analysis, 50 (32.5%) of 154 participants reported forced displacement at baseline and 62 (40.3%) stopped reporting homelessness during follow-up. In the proportional hazard MSM, confiscation of belongings (adjusted hazard ratio [AHR]: 0.35; 95% CI [0.13, 0.94]; p = 0.036) and forced displacement (AHR: 0.07; 95% CI [0.02, 0.20]; p < 0.001) were both negatively associated with transitioning from homelessness. Main limitations include potential overestimation of rates of transitioning from homelessness and limited causal inference due to the observational study design.
conclusionsThe confiscation of personal belongings and forced displacement might undermine pathways to housing. Our findings underscore the need for policy approaches that prioritize access to dignified and affordable housing rather than practices that perpetuate homelessness. Future research should assess the quality of housing that unhoused people are placed in and examine how it relates to returning to homelessness.
