Between-study comparison (1-vs-rest comparison), any p<10⁻⁶		142,899	785
*Remaining*		*184,449*

*SNPs that were not removed due to any other criterion than the one listed.

**The number of SNPs in the largest study (SCZ-SW). All other numbers refer to this number and not the number of SNPs available in each study.
