Figure 1. Comparison of predictivity of gene expression microarrays (GE) with other modalities.

The results are based on 151 comparisons of gene expression with various modalities for various datasets/tasks. Predictivity is measured by the area under ROC curve (AUC). The results in (a) are obtained using statistical comparison of AUC differences in individual datasets/tasks, while the results in (b) are obtained using nominal comparison of AUC difference in individual datasets/tasks.
