Table 9.

Characteristics of the lymph nodes missed by the system’s automatically defined stations

	Nodes missed by LNSM (36 nodes)			Ground-truth database (852 nodes)
	Mean	Min	Max	Mean	Min	Max
Long-axis length (mm)	9.0	4.2	21.3	13.1	3.3	83.8
Short-axis length (mm)	4.7	2.5	12.1	5.9	1.3	35.4
Volume (mm³)	191	21	1,473	689	12	60,095
Distance from station (mm)	4.2	0.5	27.0	–	–	–

The portion of the table labeled “Nodes Missed by LNSM” profiles the 36 nodes mislabeled by the LNSM’s automatically defined stations, while the portion of the table labeled “Ground-Truth Database” profiles the characteristics of the 852 nodes contained in the ground-truth database. The parameters “long-axis length,” “short-axis length,” and “volume” refer to the long-axis length, short-axis length, and volume of a node, while “distance from station” refers to the shortest distance of a missed node to its proper nodal station
