CNV, Copy number variant; p sz, the p value of the main effect of the CNVs on schizophrenia disease status tested with a t test; p IQ, the p value of the main effect of the CNV measures on IQ, investigated with ANOVAs in which the CNV measures, disease status and the CNV × disease status interactions were included as factors in the analyses; p interaction, the p value of the interaction effect between the CNV measure and disease status on IQ.
