Power to detect association to SNP rs901824 (a) and SNP rs603446 (b). Power for association statistics on chromosome 11. Power was calculated at α = 0.05 significance level. LRT1, likelihood-ratio test additive model; LRT2, likelihood-ratio test general 2-df model; S1, conditional score additive model; S2, conditional score general 2-df model; C1, combined conditional score additive model; C2, combined conditional score general 2-df model.
