Table 7. Numbers of significant SNPs (P-value <0.01).

	CPMA	LRT-Sum with Approach 2 (overlap)	Wald-Sum with Approach 1 (overlap)	Wald-Sum with Approach 2 (overlap)
With assumption	47	57 (46)	48 (47)	57 (46)
Without assumption		52 (43)	46 (45)	52 (43)

“With assumption”: assuming each SNP is already known to be significant for one trait, then testing whether there is at least one more significant association; “Without assumption”: directly testing whether there are at least two significant associations for each SNP; “Overlap”: the numbers of the significant SNPs that are also among the 47 detected ones by CPMA (“With assumption”).
