Impact of Cold Weather on Setup Errors in Radiotherapy

Table 2

Comparison of translational errors between the two groups.

Group	Number of CBCT	Translational errors
		X	Y	Z
Cold weather group	26	0.16 (0.06, 0.32)	0.25 (0.17, 0.52)	0.35 (0.21, 0.47)
Usual weather group	112	0.14 (0.08, 0.29)	0.23 (0.13, 0.37)	0.18 (0.1, 0.35)
U		1444.5	1264	935.5
		0.95	0.296	0.005

There was a significant difference in Z-axis translational error between the two groups ().
