Publication over time of PubMed papers pertaining to search terms PGx (‘pharmacogenomics’ OR ‘pharmacogenetics’) and/or ‘genome-wide’ (GW). The dominance of the GW approach in PGx-related research (papers) has increased about fourfold over the last few years, from approximately 3% in 2004 to about 11% in 2012, with the dominance (over the same period) of PGx research in the GW research domain remaining about the same (around 1–2%). This demonstrates that the GW approach has drastically influenced PGx research.
