Figure 8From: A Normalized Tree Index for identification of correlated clinical parameters in microarray experiments Cluster tree of the BBCP data set. The cluster tree obtained from the BBCP data set is colored and evaluated with respect to the clinical parameters estrogen receptor IHC, progesterone receptor IHC, grading, and nursing. The p-values < 0.001 indicate that the microarray data is highly correlated with the first three parameters, whereas there is no correlation with nursing.Back to article page
