Note: The column labeled “N (Replication N)” lists the number of subjects in each study, or in the Stage 1 sample if the study included a replication study. The number of subjects in the replication sample is provided in parentheses if applicable. The effect size of the largest association is provided in the last column, as a percentage of endophenotype variance accounted for. For studies including a replication sample (and analyzing discovery and replication samples separately), the variance accounted for in the replication by the variant is provided in parentheses. To avoid redundancy, we did not include GWAS results from the 17 endophenotypes examined in our special issue of Psychophysiology, which are summarized in Table 2, despite representing a different set of endophenotypes. In addition, we did not include results we obtained for event-related theta power described in section 5.2, although this measure that appears in this table.
