Between-dataset correlation of pathway t-statistics. In each scatterplot, Pearson correlation coefficient and linear regression line are shown. Quadrants are indicated as Roman numerals. Pathways in the quadrants II and IV are the discordant pathways. A large red circle denotes an exemplar pathway (MAPK signalling pathway) which is further discussed in the main text. For ASSESS, four outlier data points (with absolute t-statistics of 40 - 70) were removed to keep all six plots under a comparable scale.
