PubMedChronology

PubMedChronology (PMC) is an app to visualize the chronology of subject terms based on PubMed queries. The number of hits for certain search terms is displayed as a graph in dependence of a range of year dates.

The app is useful to analyze trends in publication topics to elucidate historical developments and/or compare importance of subjects over time.
