Each data set consisted of 200 cases and 200 controls (400 cases and 400 controls for the cases of 1,000 markers). Power corresponding to blank cells was not calculated because of being too computationally intensive. The combinatorial searching method searched up to three-locus combinations. For each scenario, the highest power is in bold.
