  1. -Total Number of variables in the non longitudinal module; which is a common module between the two Registries; is 65 with 4 identifiers so, we assessed 61 variables with 6 variables which are mandatory to complete and 55 which are optional
  2. -The core data mean the data that need completion in order to consider a case for a study. It contains the 4 identifiers, 3 mandatory variables (year of birth, Original Sex Assigned, Karyotype, and disorder type) and 2 optional variables (age at presentation and actual diagnosis)
  3. -Total number of variables in the longitudinal module in the I-CAH Registry is 47
  4. n number of variables
  5. n1 number of cases
  6. n2 median number of cases per centre (range)
  7. n3 number of centres
