Racial Climate on Willingness to Participate in Clinical Research.
Article in Journal of racial and ethnic health disparities, 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
objectiveIn the USA, there are striking racial and ethnic disparities in health outcomes particularly among African American individuals, compared to White individuals. Despite these disparities, recruiting African American communities for clinical research remains challenging. Using the socio-ecological model as a framework, this project examined whether the racial climate of the geographical area-including police shootings, neighborhood vulnerabilities, and individual trust in research institutions, is significantly associated with willingness to participate in clinical research.
methodsWe analyzed data from the University of Florida HealthStreet registry, assessing community perceptions of clinical research participation. Data was aligned with Fatal Encounters police shootings and the Social Vulnerability Index by county and zip code.
resultsParticipants had an average age of 43.01 years (SD = 16.32) with an average education of 13.04 years (SD = 2.35). The majority were female (64%) and identified as Black/African American (56.2%). Multiple logistic regression results showed that higher rates of police shootings were significantly associated with lower willingness to participate in studies involving taking medicine (b = - 0.124, se = 0.055, p < 0.05), providing samples for genetic studies (b = - 0.001, se = 0.000, p < 0.05), and use of medical equipment (b = - 0.021, se = 0.001, p < 0.001) among African American adults compared to White participants. Higher social vulnerability was associated with a lower willingness to participate in clinical research. DISCUSSION: Socioecological factors' contribution to clinical research participation among African American communities is poorly understood. Our findings highlight the need to address these factors to improve community engagement and reduce the diversity gap in clinical research.
