1 · What the graph read from it

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.

2 · The registry

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

purposeParticipation in clinical trials among people who use drugs (PWUD) in rural areas remains disproportionately low compared to those in urban communities. Our objective was to describe the barriers and facilitators to clinical trial participation among this understudied and underserved population.

methodsWe conducted semi-structured in-depth interviews among rural PWUD in Kentucky, Ohio, and Oregon. Using the Ickovics and Meisler framework, we classified factors associated with participation in clinical trials among rural PWUD into five categories: the individual, trial and intervention characteristics, participant-trial staff relationship, clinical trial setting, and features of the disease. We used inductive qualitative analysis methods to identify salient themes.

findingsThirty-five rural participants (median age: 39, 51% men) completed in-depth interviews. Facilitators for rural clinical trial participation were mainly situated within the individual, trial and intervention characteristics, and clinical trial setting. Individual characteristics, such as altruistic motivations to help their communities and peers, as well as trial and intervention characteristics like visit reminders and resource assistance, were the most frequently noted facilitators of clinical trial participation. In contrast, participation barriers were mainly related to participant-trial staff relationships and disease features. Judgmental and untrustworthy trial staff, along with involvement in the criminal legal system, were obstacles to clinical trial participation.

conclusionsIndividual, intrapersonal, and logistical factors described by rural PWUD must be addressed to enhance the participation and retention of this population in clinical trials. Successful clinical trial participation may contribute to equitable access to essential health services by PWUD in rural communities.
