  1. Power is the percentage of replicates in which the main or interaction effect of the respective marker had an adjusted p-value ≤ 0.05.
  2. aMinor allele frequency among controls
  3. bLD values calculated using the control population in Replicate 1
  4. cModel 1, main effect of one SNP at a time
  5. dModel 2, interaction term with sex of one SNP at a time
  6. eModel 3, main and interaction with sex of one SNP at a time
  7. fModel 4, stepwise model with main and interaction effects of all SNPs
