The data are presented as the Pearson correlation squared (R²); inverse correlations are indicated with a minus sign placed before each number. Correlations that are significantly different to zero are shown in a bold font and those relationships that are similar in both tissue types are shaded. The significant correlations (with p-values) are shown graphically in Figure 3.
