Impact of Cold Weather on Setup Errors in Radiotherapy

Table 4

Comparison of translational errors between the two groups.

Group	Number of CBCT	Translational errors
		X	Y	Z
Cold weather group	33	0.17 (0.09, 0.29)	0.21 (0.10, 0.40)	0.17 (0.07, 0.31)
Usual weather group	115	0.13 (0.06, 0.3)	0.23 (0.11, 0.39)	0.22 (0.08, 0.32)
t		1732.5	1769.5	1701.5
		0.447	0.555	0.366

There was no significant difference in X, Y, and Z translational errors between the two groups ().
