  1. Classification result shown separately for ASD patients or the residual patients applying the identical classification algorithms as for the total group of patients. *Simultaneous classification non-POEE/POEE for one patient increases line sum above 100%. ASD, atrial septal defect; POEE, postoperative effusions and edema.
