Cytokines that were significantly altered (p < 0.05) when unprocessed blood was stored at either room or refrigerator temperature for 24 h. Unprocessed heparin plasma stored at room temperature (a); unprocessed serum stored in the refrigerator (b); unprocessed serum stored at room temperature (c); and unprocessed haparin plasma stored at room temperature (d). Dashed lines represent data for each individual subject and the solid line represents the predicated average change for all subjects.
