The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1998 to June 2008, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and Thomson Reuters’ journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Here our ranking in pharmacology is by citations per paper – among nations that earned 15,000 or more citations during the period – to reveal weighted impact. For articles with multiple authors from different nations, each nation receives full, not fractional, citation credit. Essential Science Indicators lists nations ranked in the top 50 per cent for a field over a given period, based on total citations. In pharmacology, 88 nations are listed, meaning 176 were surveyed. Twenty-four nations collected at least 15,000 citations during the period.
