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

backgroundInclusion of minorities in clinical research is an essential step to develop novel cancer treatments, improve health care overall, understand potential differences in pharmacogenomics and address minorities' disproportionate cancer burden. However, Latinos and other minority groups continue to be critically underrepresented, particularly in early-phase clinical trials (EPCTs). The objective of the present study was to explore barriers and promoting factors influencing patients' decisions to enroll or not in early phase clinical trials (EPCTs) and identify areas for intervention to increase minority enrollment into clinical research.

methodsAn interviewer-administered survey was conducted with 100 cancer patients in the predominantly Latino region of South Texas. Exploratory factor analysis was conducted to identify underlying dimensions, and multiple logistic regression assessed significant factors that promote or deter patients enrollment to EPCTs. In addition, a separate subgroup mean analysis assessed differences by enrollment status and race/ethnicity.

resultsFor one standard deviation increase in the importance given to the possibility of symptoms improvement, the predicted odds of refusing enrollment were 3.20 times greater (OR=3.20, 95% CI=1.06-9.71,

conclusionThis study, one of the first to identify South Texas patients' barriers to enroll in EPCTs, highlights potential focal areas to increase participation of both minority and non-minority patients in clinical research. Culturally tailored interventions promoting patient-centered care and bilingual, culturally competent study teams could solve common barriers and enhance Latinos' likelihood of joining clinical trials. These interventions may simultaneously increase opportunities to involve patients and physicians in clinical trials, while ensuring the benefits of participation are equitably distributed to all patients.
