Correlations between protease inhibitor-treated fresh blood and dried-blood-spot immunosignatures at 25.0°C and 37.8°C^a

Storage time	Correlationb
	25.0°C	37.8°C
Fresh serum	NAc	NA
Overnight	0.85	0.85
1 wk	0.85	0.86

^aMicroarray summary statistics were calculated using GeneSpring (version 7.3.1) and Microsoft Office Excel 2003 software. Raw fluorescence intensities from the average of triplicate arrays were used. Replicate dried-blood spots were collected from a human donor. These samples were run on the CIM10Kv2.0 library.

^bThe correlation between the dried-blood spot and the fresh serum is the Spearman correlation, which considers only the relative rank of array features.

^cNA, not applicable.
