The Mental Roots of Performance: A Preliminary Meta-Analysis of Cognitive Genes and Athlete Status.
Synthesis in Molecular neurobiology, 2025. 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
Genetic polymorphisms play a crucial role in regulating the physiological mechanisms underlying athletic performance, including muscle structure, energy metabolism, and cognitive functions. In recent years, increasing attention has been directed toward genetic variants that may influence cognitive traits such as motivation, stress tolerance, and attention, which are critical for optimal athletic performance. The present study aimed to provide the first preliminary meta-analysis of the association between athlete status and specific candidate polymorphisms related to cognitive processes (COMT rs4680, BDNF rs6265, OPRM1 rs1799971, and APOE rs7412/rs429358). A total of 17 case-control studies meeting the inclusion criteria were retrieved from relevant databases and included in the analysis. Statistical evaluations were performed using random- and fixed-effects models with a 95% confidence interval. The results indicated a potential association between the COMT Val158Met polymorphism and athlete status in both the overall and power athlete subgroups (p < 0.05). In contrast, no significant associations were observed for BDNF rs6265, OPRM1 rs1799971, or APOE rs7412/rs429358. However, this finding is based on a small number of studies and must be interpreted as exploratory. While this preliminary meta-analysis highlights a significant evidence gap, it also underscores, due to methodological limitations, the need for further empirical studies to understand the potential role of these polymorphisms in athlete status.
