Results of sensitivity analysis for SNP grouping analysis showing the relationship between the group linkage disequilibrium parameter (<i>r</i>²) and the number of index SNPs identified, with <i>r</i>² ranging from (a) 0.05 to 0.95, and focused on the range from (b) 0.01 to 0.15.

<p>Results (c) show the relationship between the minimum statistical significance parameter for the association between the disease and the index SNP and the number of index SNPs identified.
