Mean and median clearances observed for each inked margin. In some patients the margin status was specified as positive or negative for each of the increments, but the precise distance between the margin and the tumor cells was not clearly specified

Inked margins (number of patients with a specified distance in mm)	Mean clearance (mm ± SD)	Median clearance (mm; range)
Pm (129/150)	5.6 ( 7)	3.00 [0.10–35.00]
PVSMVm (115/150)	6.8 ( 6.9)	3.00 [0.10–20.00]
SMAm (123/150)	9.0 ( 9.6)	5.00 [0.20–30.00]
«Vascular» margin (PVSMVm + SMAm; 106/150)	5.8 ( 6.6)	2.25 [0.10–20.00]
