Figure 2.

Three-way interactions between race (AA vs. CA) tumor (tumor vs. normal), and source (SBU vs. WU) for the miR-182 qRT-PCR data. Patients were classified into 8 groups (each group is determined by a combination of race, tumor and source) for their miR-182 relative expression level as measured by RT-PCR. For each data source, 4 associated group means were plotted in one figure, with a dot and triangle indicating race and an x-axis indicating normal and tumor. Additionally, the change in group means of CA patients between normal and tumor is signified by a solid line, while a dashed line represents this change in AA patients.
