P1: International Endogene Consortium (IEC) Endometriosis data p-value; P2: International Headache Genetics Consortium (IHGC) migraine data p-value; SNP: single nucleotide polymorphism; OR: odds ratio for the effect direction concordance association test for endometriosis and migraine; P: Fisher’s exact p-value for the effect direction concordance association test between endometriosis and migraine.
