A Examples of different platforms to obtain gene expression values. The venn diagram illustrates that certain prediction models are either unavailable or lack predictive accuracy when applied to data from particular platforms. B An illustration to show that gene expression values from different platforms are not comparable due to variations in chemistry, quantification, and normalization techniques used by each platform. C Illustration of a rank-based tree. D The methodological framework utilizing rank-based trees
