Figure 2

Quantile-quantile-plots (QQ-plots) comparing the distribution of gene expression values from microarrays of all investigated studies before and after the respective application of MRS or QD. One microarray per study was selected and a quantile-quantile plot (QQ-plot) for every pair of microarrays from corresponding studies was produced. In every QQ-plot the quantiles of all gene expression values of a first microarray are plotted against the quantiles of all gene expression values of a second microarray. If the gene expression values of the two different microarrays share the same distribution, the points in the plot should form a straight line. Abbreviations: MRS, median rank scores; QD, quantile discretization
