Figure 1.

Two-way hierarchical clustering of blood transcript modules (BTM) and blood informative transcripts (BIT) by individual and time. Each row represents one patient on the day indicated by the last number of the label, and each column is the principal component (PC1) score for a BTM, with co-clustered BIT PC1 highlighted. The red-to-blue scale indicates positive to negative scores. The figure highlights the tendency of the samples to cluster by individual and provides an overview of the axes of variation shared by particular patients.
