Summary of Discriminating Errors for Serum and Plasma Markers.

	Mean	Standard Deviation	Min	1st Quartile	Median	3rd Quartile	Max	p-value
Recursive Partitioning Models								<0.001
Serum	.119	.085	0	.05	.10	.15	.40
Plasma	.170	.100	0	.10	.15	.25	.45
Random Forest Models								<0.001
Serum	.081	.050	0	.05	.10	.10	.25
Plasma	.097	.060	0	.05	.10	.15	.30

Significant differences between serum and plasma for both the recursive partitioning and random forest models were tested using the Wilcoxon Rank Sum test.
