Table 6.
Percentage of relevant correlations between corresponding replicates of mass spectra measured for individual S. aureus strains depending on the matrix and culture medium calculated using the Spearman correlation method. NC: significant correlation between non-corresponding assays). An increase in the color intensity in the column means a higher value for the parameter.
