To verify the findings in the VAND sample, we genotyped the same 10 SNPs in the VAANX sample and conducted sex-stratified analyses directly. For rs2023239, we were able to replicate the female-specific association with SI (main effect P=.01 and sex effect P=.02); rs6928499 showed a trend of association with SI in the same sex (Table 5). For both SNPs, the associated alleles were the same in the 2 samples; rs806368 was nominally significant in the women for the FTND.
