Scientific literature among smoking and respiratory system: repercussion and collaboration.

a b s t r a c t Aim: To analyze the distribution of the production, repercussion and co-authorship of articles on smok- ing in the "respiratory system" category through the Science Citation Index Expanded (SCI-E) and their inclusion in the first quartile of the Journal Citation Report (JCR). Methods: The literature search was performed in the SCI-E. Articles were selected for 2001-2010 for "respiratory system" using the descriptors "smok*" and "tobac*". Results: We found 1858 articles (ignoring collaboration) on the topic of smoking. The median number of published articles by five-year period was higher for the 2006-2010 period vs the 2001-2005 period; in contrast, the number of citations and the citation index was higher for documents published in the first five-year period. Some 40.47% (ignoring collaboration) of the articles (752 documents, ignoring collaboration) were published in first quartile journals. We found very well established and cohesive co-authorship networks. Conclusions: Articles on smoking in the area of respiratory medicine increased in this time period, with 40% of the total documents in journals in the first quartile of the JCR. The citation rate was high, with the EU-27 countries having higher impact and repercussion. We found very well established and cohesive co-authorship networks.
