  1. Mildly abnormal is defined as >95th or < 5th percentile of the healthy subset, moderately abnormal as > 97.5th or < 2.5th percentile and severely abnormal as >99th or < 1st percentile of the whole sample
  2. BSA body surface area, LA left atrium, RA right atrium, RV right ventricle, TAPSE tricuspid annular systolic plane excursion
  3. aNot recommended due to negligible difference between the healthy subset and general population, see Limitations
