The table shows data of the four different 10-pulse protocols. All data are shown as average with standard deviation, and include the percentage of IRE values compared with a control. Cell number is the average number of VSMC nuclei identified in the Tunica Media. Concentration is the ratio between the number of cells and the area of the Tunica Media (10⁻³ mm²). Area is the total area of the Tunica Media (10⁻¹ mm²), and the thickness is the thickness of the Tunica Media based on five different measurements in each section in micrometers.
