The percent increased and percent decreased indicate the percentage of serum samples (of the total number of samples) that elicited a significant increase or decrease in XAR/XARcomp activity, respectively. In each independent assay, the significant activity differences between the triple F1 fraction determinations and their respective solvent controls (percent increased and percent decreased) were determined by the Student’s f-test and t-test using Microsoft Excel (Microsoft Corporation, Redmond, WA, USA) (p ≤ 0.05).
