Simulation of fold-change (FC) validation (difference boxplots). Box plots of differences (sampling method minus full benchmark sample) for the 1000 simulations are shown for (A) slope, (B) y-intercept, (C) precision (Pearson r), (D) accuracy and (E) concordance correlation coefficient (CCC). In each boxplot graph, the dotted line at 0 represents perfect agreement. The lines of the box plots represent: orange (random-stratified), green (random) and blue (top-ranked).
