Performance Metrics from OPLS-DA through a Repeated Double Cross-Validation Process

Metric	Training		Validation
	Value	p Value	Value	p Value
AUROC	0.980	<0.01	0.977	<0.01
Accuracy	0.928	<0.01	0.923	<0.01
Sensitivity	0.874	<0.01	0.867	<0.01
Specificity	0.978	<0.01	0.975	<0.01

Value columns are the mean value; p value columns were obtained from permutation tests.
