Figure 5.

Venn diagrams displaying differentially expressed probe sets that intersect or non-intersect between different comparison groups. A. Applying a FDR p-value < 0.05 and FC > 2.0 results in 95 differentially expressed probe sets (Supplement Table 1) that intersect between the four comparison groups brain metastatic PTC vs. non-brain metastatic PTCs, brain metastatic PTC (TR) vs. non-brain metastatic PTCs, brain metastatic PTC vs. primary brain tumors, and brain metastatic PTC (TR) vs. primary brain tumors. The 95 probe sets include 90 genes represented by one probe set each, 2 genes represented by two probe sets each, and one unmapped transcript. B. Applying the unadjusted p-value < 0.05 and FC > 2.0 results in 429 differentially expressed probe sets that intersect between the comparison groups as outlined under A (Supplement Table 1). Numbers of probe sets that are differentially expressed in each comparison group are given in parentheses.
