  1. aConfirmation rate = number of confirmed CNVs divided by number of detected CNVs by each array, expressed in %.
  2. bConfirmation rate = number of confirmed gains divided by number of detected gains by each array, expressed in %.
  3. cConfirmation rate = number of confirmed losses divided by number of detected losses by each array, expressed in %.
  4. dConfirmation rate = number of confirmed de novo CNVs divided by number of detected de novo CNVs by each array, expressed in %.
  5. eDe novo or inheritance unknown (parents not systematically tested).
  6. fConfirmation rate = number of confirmed inherited CNVs divided by number of detected inherited CNVs by each array, expressed in %.
