Fig. 1From: Potential unfavorable impacts of BDNF Val66Met polymorphisms on metabolic risks in average population in a longevous areaComparison of genotypic and allelic frequencies of the BDNF Val66Met among groups. a Genotypic frequency under co-dominant model, females in CG represented more AA genotype than males (Chi-square test, χ 2 = 11.263,P = 0.004). b Genotypic frequency under dominant model, no difference among groups and between sexes. c Allelic frequency, no difference among groups and between sexes. *P < 0.05.
