interaction groups, along with summaries of the respective interaction types, sources, supporting publication PMIDs and a ranking. Users interested in a particular interaction can navigate from the interaction search results to the corresponding interaction group view. Similarly, detailed information about an interacting gene or drug can be found in the associated gene or drug group view (Supplementary Figure S3). These new group views feature (i) a summary tab, which details all relevant information collected from the various source claims (e.g. aliases, FDA approval status, supporting publications); (ii) an interactions tab (for gene and drug group views), which lists summary panels of each interaction in the DGIdb for this gene or drug; and (iii) a claims tab with detailed information about each claim supporting the group.
