Further details of the search strategies and studies included are available in the online supplement (please see Web appendix, http://links.lww.com/HJH/ A130).…”

The medline UK filter: development and validation of a geographic search filter to retrieve research about the UK from OVID medline

It is challenging to develop a geographic search filter because geographic details are not always reported in titles or abstracts and controlled vocabulary terms for geographic locations are often not applied, or not applied well, in bibliographic databases …”

“…The search found two validated geographic search filters. One for Spain, which was developed for PubMed and medline and one for Africa, which was developed for both PubMed/ medline and Embase (platform details not provided) . The filter for Spain was validated using a gold standard set containing published clinical trials on myocardial infarction, and it had 88% recall .…”

Después de una búsqueda exhaustiva con el filtro geográfico para la identificación de estudios españoles de Valderas y cols 9 hemos recuperado 8 estudios. Sin embargo, prácticamente todos ellos se han realizado con bases de datos internacionales, procedentes de Reino Unido y Canadá [10][11][12][13][14][15][16][17] .…”
