Fig. 1From: Predicting combinative drug pairs towards realistic screening via integrating heterogeneous featuresThree scenarios in predicting drug combination. Nodes are drugs, among which known drugs are labeled by ‘A’ ~ ‘E’ and new drugs are labeled by ‘x’ and ‘y’. Edges, represented by solid lines, denote approved combinations between drug pairs. Dotted lines show the three scenarios for prediction corresponding to S1, S2 and S3. The drugs involved in the prediction, are filled with colorsBack to article page
