Measuring (Mis)trust in the age of COVID-19: viewpoints of vaccine clinical trial participation among individuals living with sickle cell disease.
Article in BMC public health, 2025. 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
backgroundCOVID-19 vaccine efficacy was determined by the participation of individuals from diverse backgrounds in clinical trials. While these trials recruited participants with chronic conditions, little is known about how sentiments of mistrust affected the views of vaccine trial participation. The aim of this study is to examine the relationship between self-reported institutional medical mistrust and views on the importance and utility of COVID-19 vaccine research participation among adults living with sickle cell disease (SCD) in the United States.
methodsThis cross-sectional study is part of a larger longitudinal study aimed at understanding the lived experiences of individuals living with SCD in the United States during the COVID-19 pandemic. Data from the first wave of the longitudinal study, collected June- December 2020, were used for the analyses (n = 185). Two single-item variables ascertaining the utility of participation in clinical trial research for COVID-19 vaccines were examined. Institutional medical mistrust was measured utilizing a modified medical mistrust index. Multivariable binary logistic regression models were utilized, adjusting for applicable sociodemographic, behavioral, and clinical variables.
resultsA majority of study participants agreed with statements regarding beliefs about the importance of participating in vaccine research (71.4%) and the utility of vaccine research for family and self (60.0%). Findings indicated that having any level of worry of COVID-19 infection was significantly associated with greater agreement with the importance of participating in COVID-19 vaccine research (OR = 3.41, 95% CI 1.346-8.641, p = 0.01) and higher agreement with the utility of vaccine research for themselves and their families (OR = 3.54, 95% CI: 1.332-9.403, p = 0.01), after adjusting for covariates. Agreement with the utility of vaccine research participation was also found to be associated with higher SCD severity (OR = 1.26, 95% CI: 1.043-1.537, p = 0.02). In contrast, higher medical mistrust was inversely associated with agreement of this statement (OR = 0.44, 95% CI: 0.222-0.89, p = 0.02).
conclusionsOur findings reveal that for individuals living with sickle cell disease, the worry of infection and the severity of their individual disease were more important in shaping views towards vaccine research participation than medical mistrust.
