Japan's Contribution to Research in Medicine in 1991-2000 / General Medicine

ABSTRACT

We reviewed the literature regarding Japan's contribution to research in medicine in 1991-2000. Japan contributed 7.6% of all articles in English listed in the Medline database. The contribution ranged from 0.6 to 11.4% for various clinical science fields and 3.8 to 11.9% for basic science categories of reputable journals. The lowest contributions were in the categories “General and General Internal Medicine” and “Epidemiology”, where Japan contributed only 0.6% and 1.1% of the articles, respectively. The Japanese contribution to high quality clinical research (randomized controlled trials, case-control studies, cohort studies) was meager, while that to the basic sciences was more satisfactory than to the clinical science categories. Appropriate academic and social initiatives should be made to accelerate clinical research in Japan.
