Table 2.

Errors compared following trajectory adjustments

	“+” setup	“x” setup	Stage move	P
	(n = 47)	(n = 20)	(n = 20)	value
x coordinate	0.29 (0.35)	0.38 (0.55)	0.16 (0.33)	0.36
y coordinate	0.39 (0.42)	0.51 (0.39)	0.34 (0.51)	0.69
Radial error	0.51 (0.52)	0.66 (0.72)	0.51 (0.73)	0.61

This table illustrates the median (IQR) error following each method of adjustment, x and y coordinate errors are absolute errors. No statistically significant differences were found comparing x and y coordinate errors or radial errors. The largest numerical errors were found following adjustments made using the “x” setup.
