Trust in addiction treatment services among people who use drugs in Vietnam.
Trial report in Journal of substance use and addiction treatment, 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
backgroundAlthough trust in addiction treatment providers and trust in treatment services are related yet distinct constructs, the latter remains underexplored. In Vietnam, where addiction treatment is transitioning from punitive models to community-based harm reduction, research on trust in treatment systems is particularly limited.
methodsBaseline data were drawn from an ongoing randomized controlled trial conducted across three provinces in Vietnam, involving 690 people who use drugs (PWUD). Data were collected through face-to-face, computer-assisted interviews using validated and adapted measures in addiction treatment services, depressive symptoms, perceived care support, and internalized stigma related to methadone maintenance treatment (MMT). A linear mixed-effects regression model with commune-level random-effects was used to assess associations between trust in addiction treatment services and the measures of interest, including demographic characteristics.
resultsHigher levels of internalized MMT stigma and depressive symptoms were both significantly associated with a decreased trust in addiction treatment services in the adjusted analysis. Demographic characteristics and current MMT status were not significantly associated with trust. Although trust in addition services was associated with perceived care support in bivariate analysis, this relationship was no longer significant after adjusting for other factors.
conclusionThese findings suggest trust in addiction treatment could be understood not only as a function of provider-patient relationships but also in broader institutional and systemic contexts. Addressing treatment-related stigma and integrating mental health services in addiction services may be promising strategies to improve PWUD's trust in addiction services.
