Fig 1. Composite norm (standard) for the 10-year-old female sample (left, n = 47) and the 14-year-old male sample (right, n = 45), greatly reduced. Growth achieved in the x and y direction at points Nas, A, B, and Me are noted, as is the deviation from the mean in both growth axes (± SD crosses) for the anatomical landmarks of importance to clinicians and researchers.
