  1. N -number of answers, High Prior -highest priority, Rec - recommended, Acc -- acceptable, Not Rec -not recommended;
  2. Comments - additional parameters to be used systematically: (1) imbalance of transitional point. (2) transitional point to CSL. (3) sagittal segmental evaluation. (4) restricted kyphosis angle [48]. (5) wrist bone age. (6) elbow bone age.
