Top 20 Nations
AD is largely a first-world issue, and that is very apparent when one examines the top nation lists. The US dominates by far among the nations, which, given that the bulk of the researchers and institutions are also US-based, is not a complete surprise. Other nations with researchers or institutions in the top ranks also correspondingly rise to the top, such as England, Sweden, Australia, and Canada.

Overall General Information
Top 20 Scientists, Institutions, Journals, & Nations
Citation tables allow us to map compelling trends:
- Are there particular nations or institutions that might be expected to dominate research in the Topic area, and do the numbers bear out these expectations, or are there surprises?
- Who are the leading scientists and where are they located?
While these tables cannot offer a complete picture, the number of trends and anomalies that can be spotlighted or connected across categories is striking. The tables often lead to renewed perspectives to further explore and validate.
What are Special Topics?
Special Topics, from ScienceWatch.com, is designed to complement Essential Science IndicatorsSM from Clarivate in providing citation analyses and commentary for selected scientific research areas that have experienced notable recent advances or are of special current interest.
