title: Authorship, institutional and citation metrics for publications on postmenopausal osteoporosis.
abstract: BACKGROUND
  Osteoporosis is the most common metabolic bone condition that does not often become clinically clear until a fracture occurs. The objective of the current study was to analyze all publications whose titles included the term "postmenopausal osteoporosis" published during the past decade by journals indexed in the database of SCI-E.
  
  
  METHODS
  This paper analyzes two sets of data: in the first, all papers with "postmenopausal osteoporosis" in their titles indexed in the database of SCI-E in the period 2001-2011; the second, all papers published by Osteoporosis International that were indexed in SCI-E during 2001-2011. The Science of Science Tool was used to map the co-authorship networks of papers published by Osteoporosis International in 2007-2011. Only papers cited more than 100 times in the Web of Science were considered for mapping the co-authorship network.
  
  
  RESULTS
  A total number of 2,056 papers with "postmenopausal osteoporosis" in their titles were indexed in SCI-E between 2001 and 2011. The annual number of publications increased during the study period. The majority of publications came from Western Europe and North America. The number of papers published by authors based in Western Europe was about 75% greater than for North America.
  
  
  CONCLUSIONS
  More papers on postmenopausal osteoporosis were published in Western Europe than in North America. The networks of co-authorship pointed to the strategic positions of highly cited authors from Western Europe. The top eight authors contributing the majority of papers were from Western Europe. Consequently Western Europe had greater impact than North America.
