The following tables show the primary research papers on tuberculosis published between 2003 and 2005 that have had the highest number of citations in the literature. To create these tables, we queried the Scopus database (http://www.scopus.com) to search for articles that included the term 'tuberculosis' in the title, abstract or keywords. After sorting the results on the basis of citation number, we removed review articles, as well as clinical trials, epidemiological, diagnostic and methodological papers, and studies on forms of tuberculosis that affect cattle and other species. The number of citations is accurate as of 12 February 2007. The tables include every paper that has been cited at least 100, 50 and 30 times (2003, 2004 and 2005 tables, respectively).

Table 1 Highly cited research papers on tuberculosis published in 2003
Table 2 Highly cited research papers on tuberculosis published in 2004
Table 3 Highly cited research papers on tuberculosis published in 2005
