Comparison of scatter plot of electroporated area and depth by organ with electrical intensity in the phase 2 study. (a) Damaged surface area of the mucosa at 24 h after irreversible electroporation using the Image J program (version 1.8, National Institutes of Health). (b) Histologic depth scoring as follows: 1, lamina propria; 2, muscularis mucosa; 3, submucosa 1 (half above); 4, submucosa 2 (half below); 5, muscularis propria. Bar indicates median (n = 3). The Mann–Whitney U test (*p < 0.05) was used.
