  1. (a) This table summarizes the cross-tabulation between the disease status (cases vs. controls) and the location of each gene affected by CNVs (inside vs. outside a scanning window Z) in terms of subject number. x i (Z) and y i (Z) denote to the number of genes in a window Z that were affected by CNVs of the i th case and control, respectively. m 1 and m 0 denote the total number of subjects with genes affected by CNVs in cases and controls, respectively. "Affected genes" mean genes affected by CNVs in a sample. I(a) is an indicator variable taking the value 1 if a > 0 and 0 otherwise.
  2. (b) This table summarizes the cross-tabulation between disease status (cases vs. controls) and the location of each gene affected by CNVs (inside vs. outside a scanning window Z) in terms of a gene count. x i (Z) and y i (Z) denote the number of genes in a window Z that were affected by CNVs of the i th case and control, respectively. n 1 and n 0 denote the total number of genes affected by CNVs in cases and controls, respectively. "Affected genes" mean genes affected by CNVs.
