The Classification of Sini Decoction Pattern in Traditional Chinese Medicine by Gene Expression Profiling

Figure 3

192 genes, identified using the test at a Bonferroni-adjusted significance level of 0.05/4951, were clustered into 2 groups. By applying hierarchical clustering with Spearman distance and average linkage, the 12 training samples were appropriately separated into 2 groups according to the 192 marker genes. Samples L1C2, L1A3, L1C3, L1A1, L1C1, and L1A2 comprised the SDP group, and samples L1D2, L1B3, L1D3, L1D1, L1B1, and L1B2 comprised the non-SDP group. In this figure, the gene expression value used to do the clustering is the relative expressions of the labeled sample.
