Table 5:

Agreement and differences of delineation between EPI- and HASTE-DWI determined pretreatment^a

	Agreement in %	Weighted κ (95% CI)	Differences of Means	Wilcoxon Signed Rank (P Value)
HASTE-DWI observer 1 versus EPI-DWI observer 1	78%	0.12 (−0.01–0.28)	0.65	<.0005
HASTE-DWI observer 2 versus EPI-DWI observer 2	81%	0.07 (−0.04–0.18)	0.57	<.0005

^aThe delineation of primary tumors and lymph nodes is determined by using a 3-point scale: score 1 = poor delineation, score 2 = moderate delineation, and score 3 = good delineation.
