HIV-Stigmatizing Beliefs and Attitudes as a Barrier to Early PrEP Care Continuum Engagement Among People Who Inject Drugs.
Article in AIDS and behavior, 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
HIV pre-exposure prophylaxis (PrEP) is a highly effective prevention strategy, yet awareness, knowledge, and willingness to use it among people who inject drugs (PWID) remains inadequate despite widespread eligibility. Stigma, particularly HIV-stigmatizing beliefs and attitudes, may be a key barrier to engagement at early stages of the PrEP care continuum. We examine how HIV-stigmatizing beliefs and attitudes affect PrEP awareness, knowledge, and willingness among PWID. We surveyed 262 HIV-negative PWID in Los Angeles and Denver (2021-2023) and used structural equation modeling to examine associations between HIV-stigmatizing beliefs and attitudes (11-item validated scale with α = 0.899 and 1-factor structure) and three early PrEP outcomes: awareness, knowledge, and willingness, while controlling for race/ethnicity, gender, housing status, and conducted sub-analyses on willingness to use long-acting injectable PrEP. HIV-stigmatizing beliefs and attitudes were significantly associated with lower PrEP awareness (β - 0.212, p < 0.001) and less accurate knowledge (β - 0.179, p = 0.006). Accurate knowledge was associated with greater willingness to use PrEP (β 0.175, p = 0.027). Black, Indigenous, and Other Persons of Color (BIPOC) participants reported higher HIV-stigmatizing beliefs and attitudes than non-Hispanic White participants (β 0.196, p = 0.003). Over half (56%) of participants were willing to take daily oral PrEP once informed, and many were interested in long-acting injectable PrEP. HIV-stigmatizing beliefs and attitudes are associated with lower PrEP care continuum engagement among PWID, particularly through limiting awareness and understanding of PrEP. BIPOC participants reported higher levels of stigmatizing attitudes, suggesting that broader structural and intersectional stigma may shape PrEP engagement, consistent with prior research. Interventions to increase PrEP uptake should address both individual- and structural-level stigma and consider leveraging peer networks and community supports to foster resilience and improve equitable access to HIV prevention tools.
