Association between genetic ancestry and EDAR rs3827760 genotypes in Latin American populations
Article in Biomedica : revista del Instituto Nacional de Salud, 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
Introduction. The EDAR (ectodysplasin A receptor) gene is associated with the development of ectodermal structures. The rs3827760 variant is highly frequent in East Asian and Native American populations, and this study analyzes its relationship with genetic ancestry proportions in a Latin American population sample. Objective. To analyze how genetic ancestry proportions influence the distribution of single nucleotide polymorphism (SNP) rs3827760 genotypes of the EDAR gene in Latin American populations. Materials and methods. Genetic ancestry proportions were estimated using a panel of 446 ancestry-informative SNPs, applying the STRUCTURE program and univariate and multivariate logistic regression models. Results. Native American ancestry proportions showed a significant positive association with the prevalence of rs3827760 GG genotypes, while European ancestry showed a negative association. Conclusion. Native American and European genetic ancestry proportions influence the distribution of SNP rs3827760 genotypes of the EDAR gene in Latin American populations.
