Table 1.

The prediction errors (millimeters) of individual-atlas and STAPLE-based multiple-atlas approaches with respect to clinical selections in 60 patient volumes are summarized with the medians (lower and upper quartile values in parentheses)

	Multiple-atlas-based prediction using STAPLE	Atlas-1-based prediction	Atlas-2-based prediction	Atlas-3-based prediction	Atlas-4-based prediction
AC	1.07 (0.70, 1.43)	1.21 (1.02, 1.69)	1.04 (0.69, 1.42)	1.03 (0.68, 1.48)	1.21 (0.70, 1.52)
		p < 0.001	p = 0.95	p = 0.15	p = 0.02
PC	0.94 (0.66, 1.21)	1.02 (0.72, 1.39)	1.03 (0.71, 1.38)	1.10 (0.70, 1.58)	1.11 (0.76, 1.39)
		p = 0.52	p = 0.008	p = 0.008	p < 0.001
MC	0.82 (0.55, 1.14)	1.06 (0.78, 1.32)	0.91 (0.55, 1.29)	0.87 (0.55, 1.22)	0.83 (0.64, 1.13)
		p < 0.001	p = 0.05	p = 0.36	p = 0.10

The p values of Wilcoxon signed-rank tests comparing the STAPLE-based prediction errors and individual-atlas-based prediction errors with respect to clinical selections are shown.
