BACKGROUND: The extent to which articles are cited is a surrogate of the impact
and importance of the research conducted; poorly cited articles may identify
research of limited use and potential wasted investments. We assessed trends in
the rates of poorly cited articles and journals in the cardiovascular literature
from 1997 to 2007. METHODS AND RESULTS: We identified original articles published
in cardiovascular journals and indexed in the Scopus citation database from 1997
to 2007. We defined poorly cited articles as those with ?5 citations in the 5
years following publication and poorly cited journals as those with >75% of
journal content poorly cited. We identified 164?377 articles in 222
cardiovascular journals from 1997 to 2007. From 1997 to 2007, the number of
cardiovascular articles and journals increased by 56.9% and 75.2%, respectively.
Of all the articles, 75?550 (46.0%) were poorly cited, of which 25?650 (15.6%
overall) had no citations. From 1997 to 2007, the proportion of poorly cited
articles declined slightly (52.1%-46.2%, trend P<0.001), although the absolute
number of poorly cited articles increased by 2595 (trend P<0.001). At a journal
level, 44% of cardiovascular journals had more than three-fourths of the
journal's content poorly cited at 5 years. CONCLUSION: Nearly half of all
peer-reviewed articles published in cardiovascular journals are poorly cited 5
years after publication, and many are not cited at all. The cardiovascular
literature and the number of poorly cited articles both increased substantially
from 1997 to 2007. The high proportion of poorly cited articles and journals
suggests inefficiencies in the cardiovascular research enterprise.
