Figure 3. Coefficient of variation (CV) analysis demonstrates high quality of the dataset.

The main graph illustrates the CV distribution for all probes tested. In the inset graph, the data are represented by the brown line. Removal of the “probes all absent” calls (black line), which show greater signal variation, indicates that the “Present” and “Marginal” probes have even greater reproducibility, illustrated by the shift in the CV curve.
