Chart Configuration: Corrected Count²   Number of Articles³   Show Data Values?  

1. The Historical Rankings are based upon papers published as Research Articles, Letters and Brief Communications in Nature and Nature monthly research journals (excluding journals from scientific societies) from the Asia-Pacific region dating back to 2000.
2. Represents the corrected count by calculating a corrected point total for each paper from a given country as a fraction of one (up to a maximum of 1), by taking into account the percentage of authors of the paper from that country. All authors are assumed to contribute equally to corrected count, and an author with multiple affiliations is assumed to be divided equally among those affiliations. When an author gives a "present address", "permanent address" or "current address" that affiliation is assumed to not be involved in that author's contribution to the paper and is not included in the corrected count.
3. Represents the total number of articles that list authors from a given country, regardless of the percentage of authors of the paper from that country.
