Supplemental Figure 3: Correlations between miRNA array platforms. To study the correlation of the absolute fold changes between each microarray platform, the fold change data (n = 140) was Log 2 transformed, plotted and the Pearson correlation, r, calculated between platforms (Figure 3). We first compared all of the platforms to our LMT legacy platform to determine which of the commercial platforms correlates best with our reference platform. The Agilent platform demonstrated the highest correlation to our LMT array data (r = 0.882) based on absolute fold change.
