Introduction
Evaluation of published medical research remains a challenge.
Two classic yardsticks are the citation count (the number of
times a given paper is cited by others)
1
2 and the impact factor
of the journal that published the paper (which reflects the
average number of citations per article).
2
3 However, the citation
count can be assessed only several years after publication,
and the impact factor is not paper specific and is thus virtually
meaningless in assessing any given paper.
3 Another measure,
which can be obtained rapidly and is paper specific, is the
"hit count" (the number of times a paper is accessed online).
Whether this count predicts citations is unknown. I examined
this issue prospectively in a cohort of papers published in
the
BMJ.
Methods and results
The study used articles published in volume 318 of the
BMJ (1999)
in sections titled Papers, General Practice, and Information
in Practice. The hit counts (full text articles,
