Combinations of alleles, the carriage of which is associated with the risk of VVS: (A) predisposing combination COMT*G + NOS3*T and its alleles; (B) protective combination ADRA1A*A + ADORA2A*T and its alleles. Odds ratio values (dots) and confidence intervals of genetic variants (vertical segments) are presented graphically; p-values are denoted on the top. Black dots denote insignificant variants, red dots denote predisposing variants, and green dots denote protective variants.
