Statistical power estimated using 200 cases and 200 controls across a range of experimental settings. x-y coordinates of the numbers within the plot represent number of causal SNPs and power respectively for individual simulated examples. Relative risks (RR) are denoted by the numbers themselves. Cases with the same RR value and MAF of 0.25 are linked using solid lines while those having MAF of 0.05 are joined by dashed lines. The lines are colored grey if causal SNPs were not genotyped; black otherwise.
