The influences of genetic polymorphisms in three candidate genes on the athletic performance of Korean athletes.

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
backgoundIt is known that in addition to environmental factors such as the athlete's own efforts or the qualities of the coach, genetic predisposition can also have a significant impact on achievements in the sports field.
objectiveFor this reason, this study tried to analyze whether single nucleotide polymorphisms (SNPs) in the myostatin, hemochromatosis(HFE) and estrogen receptor 1 (ESR1) genes, which are known to affect muscular strength, cardiorespiratory endurance and flexibility, respectively, could significantly affect the athletic performance of endurance or power/sprint events in Korean population.
methodsA total of 192 Korean unrelated participants were recruited in this study. They were divided into two groups: controls (n = 72) and track-field athletes (n = 120), which included throwing athletes (n = 39) and distance runners (n = 81). Also, the determination of the genotypes constituting the SNP markers in the three kinds of candidate genes mentioned above was performed using TaqMan method.
resultsAmong the three kinds of SNP markers studied, only the rs1799945 polymorphism in the HFE gene was observed to be significantly associated with endurance performance in Korean athletes (p < 0.05).
conclusionTherefore, our results suggest that the rs1799945 polymorphism in the HFE gene may be one of useful genetic markers for endurance performance in Korean athletes. Further studies using larger sample sizes and various sports events are needed to replicate our results.
