Area under the ROC curve for different tests.

Variable	Area	Confidence interval to 95 %		P-value
		Low limit	Top limit
NPC recovery	0.929	0.855	1	<0.001
BAF	0.886	0.797	0.976	<0.001
NPC break	0.816	0.704	0.928	<0.001
MAF	0.814	0.704	0.925	<0.001
VF	0.787	0.672	0.901	<0.001
MEM	0.714	0.589	0.839	0.003
