Geometric (region volume) and dosimetric (dose delivered on average to the regions) characterization of the lung regions showing a statistical significant difference between groups (P<.05) according to the 3 applied statistical schemes

S volume, cm³	Statistical mapping scheme
	T			TFCE			t
	14.7			109			603
	RILD		Non-RILD	RILD		Non-RILD	RILD		Non-RILD
Median dose, Gy	2.35		1.45	5.89		3.74	8.21		5.00
Range, Gy	(0.12–8.69)		(0.03–7.10)	(0.27–13.10)		(0.03–12.41)	(0.93–12.11)		(0.33–14.95)
P value		.005			.011			.001

Abbreviations: RILD = radiation-induced lung injury; TFCE = threshold-free cluster enhancement

P values express the significance (Mann-Whitney U test) of the mean dose difference between groups of patients.
