Table 3:

Interobserver agreement and differences of delineation using EPI- and HASTE-DWI determined pretreatment^a

	Agreement in %	Weighted κ (95% CI)	Differences of Means	Wilcoxon Signed Rank (P Value)
EPI-DWI observer 1 versus EPI-DWI observer 2	98%	0.52 (0.16–0.76)	0.09	.07
HASTE-DWI observer 1 versus HASTE-DWI observer 2	90%	0.54 (0.34–0.73)	0.17	.18

^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.
