  1. SNP, single nucleotide polymorphism; OR, odds ratio; 95% CI, 95% confidence interval
  2. p values were calculated by logistic regression analysis with adjustments for age and gender
  3. p < 0.05 indicates statistical significance
  4. Bold indicates that the values have statistical significance
