Table 3

Values of the multiple linear regression model for prediction of dose-volume parameter.

	Vn	A	B	C	R^2
Bladder	V30	0.511	0.843	7.966	0.997
	V35	0.646	0.853	5.588	0.997
	V40	0.771	0.840	4.108	0.997
Rectum	V30	0.557	0.886	5.754	0.997
	V35	0.669	0.916	3.746	0.995
	V40	0.783	0.953	2.223	0.993

V_n = A × OP (%) + B × V_n-NOS + C. V_n: the percent volume covered by a dose of at least n Gy for bladder/rectum. V_n-NOS: the percent volume covered by the corresponding dose of at least n Gy for the nonoverlap bladder/rectum structure. OP: overlapped volume as a percentage of bladder/rectum volumes A, B, and C are regression constants.
