Figure 4From: Assessing the druggability of protein-protein interactions by a supervised machine-learning methodFrequency distributions of (A) the number of interacting proteins ( L ) (attribute no. 46) and (B) the number of pathways in which either protein is involved ( L ) (attribute no. 48). For both attributes, the difference between the frequency distributions of the positive and test instances is statistically significant (P < 10-15) by the two-sample Kolmogorov-Smirnov test.Back to article page
