Impact of Cold Weather on Setup Errors in Radiotherapy

Table 5

Comparison of rotational errors between the two groups.

Group	Number of CBCT	Rotational errors
		RX	RY	RZ
Cold weather group	33	1.1 (0.5, 1.8)	0.5 (0.20, 0.80)	0.5 (0.3, 0.9)
Usual weather group	115	0.8 (0.4, 1.55)	0.6 (0.25, 1.2)	0.5 (0.2, 1.05)
t		1607	1700.5	1853
		0.18	0.363	0.837

There was no significant difference in R_X, R_Y, and R_Z rotational errors between the two groups ().
