Comparación entre dos quinquenios (1998/2002 y 2003/2007) de la producción, repercusión y colaboración en tabaquismo de autores españoles a través del Science Citation Index / Comparison Between Two Five Year Periods (1998/2002 and 2003/2007) on the Production, Impact and co-Authorship of Publications on Tobacco and Smoking by Spanish authors Using the Science Citation Index

ObjetivoEl objetivo ha sido comparar entre dos quinquenios (1998 a 2002 con 2003 a 2007) la producción, repercusión y la colaboración de artículos sobre tabaquismo de autores españoles a través del Science Citation Index (SCI).MétodoLa búsqueda se realizó en el SCI Expanded. Fueron seleccionados todos los tipos de documentos y la búsqueda se restringió al “título”; palabras clave: “smok*” y “tobac*”.ResultadosFueron un total de 588 artículos, de los que 399 (67,85%) fueron originales, 54 (9,18%) cartas al director y 35 (5,95%) editoriales. La producción ha crecido, pasando de 234 (39,8%) documentos (98/02) a 354 (60,2%) en 03/07. Al comparar la media anual del total de artículos por quinquenios 98/02 vs 03/07 (47±8 vs 71±16 [p=0,024]) la diferencia es significativa, igual que si comparamos las medias anuales por quinquenios de los originales (34±6 vs 46±9 [p=0,041]). La media de citas/trabajo por quinquenios fue de 14,1±2,1 para 98/02 y del 5,6±2,5 para 03/07 (p=0,003). El índice de colaboración anual aumentó, pasando la media de 6,77 firmas/trabajo en 98/02, a 6,87 firmas/trabajo en 03/07. Ha aumentado el número de redes de colaboración de instituciones y autores.ConclusionesTanto la producción científica como la colaboración entre autores e instituciones han aumentado en el periodo estudiado. Son los artículos más antiguos los que más citas tienen(AU)

ObjectiveThe aim of this study was to compare the production, impact and co-authorship of publications by Spanish authors on smoking and tobacco between two time periods (1998/2002 vs 2003/2007) using Science Citation Index (SCI).MethodsThe literature search was performed in the SCI-Expanded on 20 November 2008. All types of documents by Spanish authors were selected. The search was restricted to the title, and the key words used were “smok*” and “tobac*”. The statistical analysis was descriptive (95% CI).ResultsA total of 588 documents were obtained, with 399 (67.85%) original papers, 54 (9.18%) letters to the editor, and 35 (5.95%) editorials. Productivity increased between the 98/02 to 03/07 periods: 234 (39.8%) documents versus 354 (60.2%). We have found significant differences between the two periods (98/02 vs 03/07) in total mean annual documents (47±8 vs 71±16 [p=0.024]) and total mean annual original papers (34±6 vs 46±9 [p=0.041]). The mean number of citations per document was 14.1±2.1 for 98/02 period and 5.6±2.5 for 03/07 period (p=0.003). The co-authorship annual index had increased; with a mean of 6.77 signatures/document for 98/02 period to a mean of 6.87 for 03/07 period. Authors and institution networks collaborations had increased between the two periods.ConclusionsSpanish production and co-authorship of documents on smoking and tobacco have increased between these two periods. The earlier period documents received more citations(AU)

Comparison between two five year periods (1998/2002 and 2003/2007) on the production, impact and co-authorship of publications on tobacco and smoking by Spanish authors using the Science Citation Index.

OBJECTIVE: The aim of this study was to compare the production, impact and co-authorship of publications by Spanish authors on smoking and tobacco between two time periods (1998/2002 vs 2003/2007) using Science Citation Index (SCI). METHODS: The literature search was performed in the SCI-Expanded on 20 November 2008. All types of documents by Spanish authors were selected.

The mean number of citations per document was 14.1 ± 2.1 for 98/02 period and 5.6 ± 2.5 for 03/07 period (p=0.003). The co-authorship annual index had increased; with a mean of 6.77 signatures/document for 98/02 period to a mean of 6.87 for 03/07 period.
