Figure 5: The top 20 prescribed drugs by Barmer in 2018 and the number of pharmacogenetic annotations in PharmGKB associated with the drug.
The different colors represent the levels of evidence. For some drugs no PharmGKB annotation exists (e.g. Levothyroxine). Whereas for Aspirin, 73 annotations are found, but most of them have a level of evidence of 3 or 4, so they do not count as significant for a medication check. The number of annotations varies strongly between the drugs.
