Summary of enrichment analysis of known drug targets in the sub-networks associated with 16 small-molecule drug responses.

x represents the number of known targets for the SMP drawn from the sub-network associated with the SMP; k represents the number of genes in the sub-network associated with the SMP; m represents the number of known drug targets for the SMP in the background gene set; n represents the number of genes in the background gene set excluded the known drug targets for the SMP; p-value is calculated as 1-phyper(x, m, n, k), where phyper is a function used in R.
