Your DNA, your concerns: public attitudes toward donation of genomic data for research in four Latin American countries.
Article in Journal of community genetics, 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
background"Your DNA, Your Say" (YDYS) is an anonymous online survey covering attitudes towards genomic and medical data sharing for research purposes. This study aims to identify factors influencing willingness to donate genetic information in Latin America and explore concerns regarding data donation.
methodsResponses to the YDYS survey were collected using a mixed recruitment strategy for participants in Argentina (N = 919), Brazil (N = 1,349), Costa Rica (N = 469), and Mexico (N = 1,347). The survey assessed willingness to donate genetic and medical data, perceptions regarding third-party access, use and disclosure of such data, levels of trust, and concerns about potential harms resulting from loss of anonymity. Sociodemographic information was also collected. Three indexes-Willingness to Donate, Know Me, and Against Me-were constructed, and regression analyses were conducted to examine associations between sociodemographic variables and these measures.
resultsWillingness to donate data is higher when profit is not involved. Concerns measured by the "Know Me" index are lower among women and individuals with a high willingness to donate, and higher for individuals with tertiary education. For the "Against Me" index, concern decreases with age and willingness to donate, and increases for people that have children, are religious, and have university education. In general, young age, having children, tertiary education level, and showing reduced levels of concern are associated with a higher willingness to donate genetic information.
conclusionsThis is one of the first studies exploring attitudes toward genetic data sharing in Latin America. This knowledge can guide strategies to ensure inclusion and diversity in future genetic studies.
