Table 4. Concordance Correlation Coefficient.

Phantom	X - coordinate	Y- coordinate	Z - coordinate
1	0.57	0.75	0.90
2	0.98	0.80	0.65
3	0.99	0.99	0.98
4	0.96	0.99	0.25^*
5	0.79	0.96	0.94
6	0.92	0.98	0.99
7	0.98	0.99	0.81
Mean	0.88	0.92	0.79
95% Confidence Interval (Lower, Upper)	(0.81, 0.99)	(0.87, 0.99)	(0.60, 0.98)

Note: The X- and Y- coordinates represent the horizontal and vertical displacement while the Z- coordinate is the depth of displacement of catheter insertion.

This result is not typical. Error in the depth of fiber insertion occurred for 1 out of the 12 catheters placed in this phantom.
