  1. a Patient numbers according to Edhemovic et al. [6], where more patients' details can be found. For patients not included in this study see the explanation in the Methods section.
  2. b The two longest perpendicular tumor diameters were estimated using ultrasound imaging during intra-abdominal surgery.
  3. c The data for voltage and current in tumor M2 in patient No. 15 was corrupted; therefore the total energy applied to the patient was estimated as twice the energy applied to tumor M1 since almost the same parameters of EP pulse delivery were used for both tumors.
