The QQ plots of 5 Psychiatric Genomics Consortium traits (SCZ, bipolar affective disorder, autism spectrum disorder, attention-deficit/hyperactivity disorder, and MDD) were stratified based on our CAD GWAS results at significance levels of P < .05, P < .01, P < 1 × 10−3, and P < 1 × 10−4. We observed enrichment of the MDD GWAS signal in the CAD GWAS (eFigure 4 in the Supplement) in European American participants, but no clear enrichment for the other 4 psychiatric disorders in either population group (eFigure 5 in the Supplement).
