Global repositioning association among ATC codes
First, we divided drugs found in the top 5% of drug pairs in the iDSN into 14 groups according to their ATC codes. Then we averaged the similarity scores between the different drug groups and used these averages as indices of the repositioning potential within each ATC code. The 14 nodes represent ATC first levels. Edge thickness represents the repositioning potential of drugs between the two ATC codes connected.
