The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This data­base 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 a journal-to-category field-definition scheme. Papers in multidisciplinary journals such as Nature or Science are assigned to a field based on paper-by-paper analysis.

This ranking is by citations per paper to reveal weighted impact. A threshold of 50 papers was employed to identify particularly active scientists. For articles with multiple authors, each author receives full, not fractional, credit. Essential Science Indicators lists authors ranked in the top 1 per cent for a field over a given period, based on total citations. For these data, 7,002 authors are listed in biochemistry: of the 7,002 authors, 2,432 published 50 or more papers during the period surveyed.
