Table 2 Distribution of interindividual variability of metabolite abundance of the 353 metabolites, measured as the Coefficient of Variations (CVs) by collection time points [T1, T2, T4: 1, 2 and 4 min, respectively, after tying the tourniquet and NT (no tourniquet with collection 5 min after removal of the tourniquet)] in 05 study participants. The CVs were calculated as the ratio of median absolute deviation about median to median of the unscaled abundance (peak intensities) of respective metabolites.

  1. T1, T2, T4 are 1, 2 and 4 min respectively, of time elapsed after tying the tourniquet; NT is no tourniquet, where blood sample collection occurred 5 min after removal of the tourniquet.
