Assessment of margin border sharpness on TUNEL

	Width of Transition Zone (um) Mean ±SD
Techniques	Liver	Kidney
Radiofrequency ablation	811 ± 477 [404–1277]	938 ± 429 [606–1365]
Cryoablation	452 ± 222 [275–541]	700 ± 563 [294–941]
Microwave ablation	319 ± 157 [199–449]	267 ± 95 [191–328]
Irreversible electroporation	1319 ± 682 [724–1863]	1570 ± 962 [923–2040]

Note - All data (in μm) are expressed as the mean ± standard deviation [interquartile range]. Transition zones were defined as regions where TUNEL staining decreased from >99% of cells to <5%.
