a Venn diagram displaying the probe sets and genes up and down-regulated in the various classes. Only genes that varied significantly (fold-change >1.5, and P < 0.05) are displayed. Numbers on top row indicate probe sets with increased expression, while numbers in lower row indicate probe sets with decreased expression. b Combined table and histogram displaying the number of genes that were expressed differentially in the three classes. The table indicates the direction of expression and the histogram indicates the number of genes expressed in the classes
