Neurogenetic Profiles of Anxiety, Impulsivity, and Personality Traits in Elite Combat Sport Athletes: A Cluster-Based Analysis.
Article in Biology, 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
Behavioral regulation in elite combat sports relies on traits such as anxiety, impulsivity, and personality, which are partly shaped by dopaminergic signaling. However, integrative approaches linking multidimensional behavioral profiles with genetic variability in athletes remain limited. This study aimed to identify distinct psychological profiles in elite combat athletes and examine whether these profiles differ in selected dopaminergic gene polymorphisms. A total of 200 male Polish elite combat athletes completed validated questionnaires assessing personality, anxiety, impulsivity, attention-related symptoms, and hedonic capacity. Standardized psychological variables were analyzed using a two-step clustering procedure. Genotype distributions were compared across clusters using chi-square tests. The clusters showed clear behavioral differentiation. Cluster 1 demonstrated higher anxiety, impulsivity, neuroticism, and attention-related symptoms. Cluster 2 showed lower anxiety and impulsivity alongside higher extraversion and conscientiousness. Cluster 3 displayed intermediate behavioral characteristics but the most distinctive genotype pattern. These findings suggest that combining behavioral clustering with genetic data may help characterize meaningful neurogenetic profiles in elite athletes and provide hypothesis-generating insights into genotype-phenotype relationships.
