Drug prescription by Wikipedia for the top 20 most influential cancer types and comparison with prescriptions by National Cancer Institute and DrugBank.

For each of the top 20 cancer types ranked in May 2017 English Wikipedia using PageRank algorithm (see Table 3), we give the three strongest cancer → drug links, i.e., for a given cancer type cr we select the three cancer drugs d with the highest values . Drug with red background indicates a pure hidden cancer → drug link, i.e., the cancer type article in Wikipedia does not refer directly to the drug. For each cancer → drug link, the drug is followed by a ✔ mark if it is indeed prescribed for the cancer type according to National Cancer Institute [25] and/or DrugBank [29]; by a ▲ mark if the drug appears only as a subject of passed, ongoing or planned clinical trials reported for the cancer type in DrugBank; and by a ✘ mark otherwise.
